phonon

代码说明：

  This program calculate the conductivity of cylindrical metal nanowire using the phonon approximation in a core-shell structure, in this code, the diameter, and the metal can be changed to simulated other metals. the calculated dispersion relation of the resistivity of a single band is saved as data file. to use the program, run g_E2.m(This program calculate the conductivity of cylindrical metal nanowire using the phonon approximation in a core-shell structure, in this code, the diameter, and the metal can be changed to simulated other metals.
