Abstract

In this paper, entropy and specific heat of a GaAs quantum wire with two different cross sections is studied. First, using the solution of Schrodinger equation, the eigenvalues and eigenfunctions are calculated analytically. Then, we have obtained entropy and specific heat of two quantum wires using Tsallis formalism. The results show that entropy and specific heat are continnus functions. Unlike classical thermodynamics, entropy and specific heat will not have any value and by a condition (cut off) is determined. For both wire, with increasing wire size the peak numbers in specific heat are changed. The stronger the quantum confinement, the thermodynamic properties of the discrete nature becomes more apparent.
