Size- And Temperature-Dependent Thermal Expansion Coefficient Of A Nanofilm

open access: yes, 2009
The thermal expansion coefficient (TEC) of an ideal crystal is derived by using a method of Boltzmann statistics. The Morse potential energy function is adopted to show the dependence of the TEC on the temperature.
