	Abstract:In this paper, the phase detection method is demonstrated to determine the films thicknesses of bimetallic layers by Surface Plasmas Resonance (SPR) prism coupler. It was proposed and developed by matching the experimental results to the theoretical curves of the phase difference with different angles of incidence. Theoretical analysis and experimental results indicate that the method proposed is stable and reliable, and feasible to be used to determine the film thickness of bimetallic layers directly with nanometer order resolution.

	Abstract:Halogen is always brought by the process of wet etching for fused silica devices, which dramatically influence the performance of the devices. Using ab initio quantum mechanical methods we investigate the adsorption properties for halogen atoms (F, Cl) on fused silica surface. We focus on the interaction mechanisms of halogen atoms with two main surface defects and make comparison for the absorption capacity of different surface defects. Furthermore, the electronic structure for impurity defects are also studied.

	3. Investigation of raw-material pre-milling effection physical properties of BaTiO3 piezoelectric ceramics

	Abstract:This paper reports our investigation result about the pre-milling treatment effect of BaCO3 powder on physical properties of the resultant BaTiO3 ceramics prepared by conventional solid-state reaction. BaCO3 powder usually consists of large rod-shaped particles, which cannot be easily broken up into fine ones when ball-milled together with TiO2 powder. This may lead to chemical compositional non-uniformity and large particle sizes of the subsequently synthesized BaTiO3 powder, and may eventually affect microstructure and piezoelectric properties of the resultant BaTiO3 ceramics. Our study showed that an additional ball-milling treatment of BaCO3 powderbefore being mixed with TiO2 powder is an effective mean to get good-quality BaTiO3 fine powder. In such a way, we fabricated a series of small-grained dense BaTiO3 ceramics with significantly high piezoelectric coefficient d33. A much enhanced d33 value of 470 pC/N was achieved in comparison to the previous maximum one of 410 pC/N for those BaTiO3 ceramics formed through ordinary ceramic procedure.

	Abstract:We have synthesized aminopropyl triethoxysilane (APTES) decorated zinc oxide (ZnO) nanocrystals, and investigated their optical property and cytotoxicity properties. Transmission electron microscopy, dynamic light scattering and X-ray diffraction analysis, demonstrated that crystalline ZnO nanoparticles had been synthesized by using sol-gel method with an average size of 8 nm. The APTES decorated ZnO nanocrystals showed a stable and broad emission band with peak position at around 540-550 nm under excitation of a 330 nm Xe-lamp line. Cell viability analysis indicated that the decorated ZnO nanocrystals had not significant influence on the cervical carcinoma cell proliferation until the concentration was up to of 20μg/mL.)

	Abstract:Organic solar cells (OSCs) have many potential advantages such as easy fabrication, low cost, light weight, good flexibility, etc. However, the power conversion efficiency (PCE) of OSCs is lower than their inorganic counterparts because the thickness of the active layer is limited due to the contradiction between the electrical and optical properties. Aiming for boosting the absorption under the existing thickness of the active layer, researchers have introduced diverse light trapping elements into OSCs, e.g., metallic nanoparticles (MNPs), as they can excite localized surface plasmon resonance. Recently, there have been a series of experimental studies dedicated to understanding the influences of MNPs on the performance of OSCs. In this work, we have successfully synthesized lipophilic Au Nanorods (NRods) by surface modifying the aqueous Au NRods using NH2-PEG-SH and then dope the lipophilic Au NRods directly into the active layer of OSCs. By this way, we have improved the PCE of OSC devices from 5.9% to 6.5%, corresponding to almost 10% improvement. The significant increase in PCE comes from the increase in the short circuit current, agreeing well with the broadband enhancement in the spectra of external quantum efficiency. Besides, the film with PEG-coated Au NRods has greater optical absorption relative to the control film, reflecting that the incorporation of the MNPs helps harnessing more incident light and thus improving PCE.

	Abstract:Many researches pay attention to the metal-semiconductor interface barrier height, due to its effect on device. Deliberate growing an interface layer to affect and improve the quality of device, especially metal-insulator-semiconductor (MIS) structures, arouse wide attention. In this paper, Be-doped GaAs was grown on substrate wafer by MBE on purpose before depositing insulator layer, and then MgO film as the dielectric interface layer of Au/GaAs were deposited using Atomic Layer Deposition (ALD) method. The interface electrical characteristics of the metal-insulator-semiconductor (MIS) structures were investigated in detail. The barrier height and ideal factor of GaAs diode parameters were calculated by means of current-woltage(I-V) characteristics. Experimental result shown that along with the increasing of the doping content, the Schottky barrier height increasing, but the ideal factor decrease at first and then increase.

	Abstract:The adiabatic approximation has applied to the study of Jaynes-Cummings model with ultra- strong coupling, introduced by Irish and Agarwal,et al.(Phys. Rev. B. 72, 195410 (2005) and Phys. Rev. A.85, 043815 (2012)), we extend Agarwal's work to include the interaction between the two qubits. We get the eigenvalues and eigenfunctions of Rabi Hamiltonian. We discuss the time dependence of two qubits considering the interaction between them. Qualitative di?erence between the Agarwal's work and ours are most interesting, and may ˉnd applications in entangled state: under ultra-strong coupling and large defuning condition, the two qubits coupled to a quantum oscillator will show the tendency of preserving their entanglement by the increase of interaction strength between two qubits.

	8. Size-dependent scaling of exchange bias in NiFe2O4/NiO nanogranular systems synthesized by a phase separation method
	Tian Zhaoming,Huang Shuai
	Physics 04 February 2013
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:Exchange bias (EB) effect has been studied in a series of nanogranular systems of ferrimagnetic (Ferri) NiFe2O4 nanoparticles embedded into antiferromagnetic (AFM) NiO matrix, synthesized by a phase pprecipitation method from diluted Ni(1-x)FexO3 (x=0.09) oxides. For these systems, the crystalline size (DNFO) of NiFe2O4 ranging from ~3 nm to ~55 nm has been obtained with thermal treated at different temperatures from 550oC to 1000oC. Magnetization measurement shows that, both exchange bias field (HEB) and vertical magnetization shifts (MShift) can be exhibited below 250 K after field cooling procedure. The HEB and MShift decrease monotonically with crystalline size, and their behavior strongly depend on the crystalline size of NiFe2O4 nanoparticles. Linear relationship between HEB and MShift is observed for systems with smaller sizes (DNFO≤8 nm), reveals a straightforward correlation between them. This phenomenon is ascribed to the interfacial exchange coupling between Ferri NiFe2O4 clusters and spin-glass-like (SGL) phases, where the frozen uncompensated spins in SGL phases play critical role of in inducing EB effect. As DNFO is above 12 nm, the dependence of HEB on MShift deviates from the linear relationship, which is discussed in terms of the superimposed contribution from the exchange coupling between Ferri NiFe2O4 core with the SGL phase, and the exchange coupling between Ferri NiFe2O4 core and AFM NiO phases at the interfaces.

	9. Plasmonic effect enhanced light capturing in TiO2-SiO2- Ag nanocomposites through Ag nanoparticles embedded in SiO2
	Xu JinXia,Xiao Xiangheng
	Physics 22 January 2013
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:TiO2-SiO2-Ag composites are fabricated by depositing TiO2 films on silica substrates embedded with Ag nanoparticles. Enhancement of light absorption of the nanostructural composites is observed. The light absorption enhancement of synthesized structure in comparison to TiO2 is originated from near field enhancement caused by the plasmonic effect of Ag NPs, which can be demonstrated by the optical absorption spectra, Raman scattering investigation and the increase of the photocatalytic activity. The embedded Ag nanoparticles are formed by ion implantation, which effectively prevents Ag to be oxidized through direct contact with TiO2. The suggested incorporation of plasmonic nanostructures shows a great potential application in highly efficient photocatalyst and ultra-thin solar cell.

	Abstract:We have carried out a gradient-corrected density functional theory calculation to investigate the structural, electronic, magnetic properties of Yn (n ≤ 20). The clusters exhibit high stability at n = 4, 7, 10, 13, 16, 18, a result of a coexistence of atomic motif and electronic ordering. The measured ionization energies are well reproduced. The average magnetic moment per atom shows a clearly size-dependent variation and is as high as 1.0μB for Y13. The measured moments can be overall understood as the average over different low-lying spin states of a given size. Ferromagnetic ordering is energetically preferred for clusters with n = 2 - 6, 13 - 15 and competes with ferrimagnetic ordering in the range n = 7 - 12. The first appearance of nonmagnetic state at n = 16 and nearly zero magnets for the sizes of n = 18 - 20 might provide an evidence that the approach to the paramagnetic nature of bulk yttrium.
