Comparison of some theoretical models for fittings of the temperature dependence of the fundamental energy gap in GaAs
Non-linear behavior of Eg(T) Zero-point energy Temperature dependence of the gap Gallium arsenide

In this work we report on a comparison of some theoretical models usually used to fit the dependence on temperature of the fundamental energy gap of semiconductor materials. We used in our investigati...

A mixed mean-field/BCS phase with an energy gap at high $T_c$
mixed mean-field/BCS phase energy gap
2010/11/1
We construct a pair potential which in a scaling limit leads to a Hamiltonian that generates co-existing mean-field and superconducting phases. Depending on the relative values of the coupling constan...
