Title: electrical conductance
Post by: Dipankar Saha on January 6, 2017, 10:54

Hi,

Does it consider the linear response approximation...whenever we calculate electrical conductance using TE coeff. plug-in ?? / What about   dI/dV   in near equilibrium??

Thanks in advance... :)

The thermoelectrics (TE) plugin calculates the transport properties of materials and material systems in the linear response approximation indeed. The dI/dV near zero bias is approximately given by the electron conductance calculated at zero bias.
