The density of states for indium arsenide (zincblende structure) was calculated using the program Quantum Espresso (version 5.3.0).
The parameters for GaP were taken from the following sites:
lattice constant
atomic properties
Bandgap in detail:
The calculated bandgap has a value of about 0.11 eV in comparison to a measured value of 0.354 eV (cf. reference value). The plots were adjusted to the right bandgap.
