Query: Relaxation time approximations in PAOFLOW 2.0   Regardless of its success, the constant relaxation time approximation has
limited validity. Temperature and energy dependent effects are important to
match experimental trends even in simple situations. We present the
implementation of relaxation time approximation models in the calculation of
Boltzmann transport in PAOFLOW 2.0 and apply those to model band-structures. In
addition, using a self-consistent fitting of the model parameters to
experimental conductivity data, we provide a flexible tool to extract
scattering rates with high accuracy. We illustrate the approximations using
simple models and then apply the method to GaAs, Si, Mg3Sb2, and CoSb3.
