Abstract:With the miniaturization of a solid down to nanometers scale, the elasticity, extensibility, Debye temperature, and the specific heat capacity are no longer constant but change with variation of size. The trends of change of these quantities also depend on temperature of measurement and the nature of chemical bond involved. Mechanism behind the intriguing tunability and the interdependence of these quantities are yet unclear. A set of analytical solutions is presented herewith showing that the observed trends could be reproduced by taking the fact of bond order deficiency into effect. Agreement between predictions and observations clarifies that the shortened and strengthened surface bonds dictate the observed variations intrinsically yet atoms in the core interior remain as they are in the bulk. | |||
