Abstract:In this paper, a novel method to determine the thickness of different thin metal film is put forward which uses Surface Plasmon Resonance (SPR) phase detection method. The relations between the metal film thickness and the phases of the transverse magnetic (TM) and transverse electric (TE) polarization of the reflected light are shown in the simulation results. By recording the interference patterns which contain the information of the phase differences in the experiments, the values of thickness are calculated. Both of the theoretical analysis and experimental results indicate that the approach presented is feasible and reliable. Thus, it is possible to use the method of phase detection to determine the thickness of different thin metal films in SPR prism couplers directly with nanometer resolution. | |||

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:GaFeO3 bulks with x from 0.7 to 1.3 have been fabricated by using classic solid-state route. The structural, optical, and magnetic properties have been investigated systematically. The results of EDX demonstrated that the Fe content can be obtained by adjusting the Fe content in the powders. XRD spectra and FULLPROF profile fitting indicated that GFO bulks belong to the orthorhombic structure with space group Pc21n. Phase separation appeared at the Fe content of x=1.3. Meanwhile, the magnetic property measurements suggested that GaFeO3 is ferromagnetic, and magnetic properties can be enhanced by increasing the Fe content, which is of vital importance for the application of ferromagnetic semiconductors. | |||

Abstract:In this paper, we construct two sets of vertex operators $S_+$ and $S_-$ from a direct sum of two sets of Heisenberg algebras. Then by calculating the vacuum expectation value of some products of vertex operators, we get Macdonald function in special variables $x_i=t^{i-1}$ ($i=0, 1, 2, \cdots$). Hence we obtain the operator product formula for a special Macdonald function $P_{\lambda}(1, t, \cdots, t^{n-1}; q, t)$ when $n$ is finite as well as when $n$ goes to infinity. | |||
