Momentum matrix element and conduction band nonparabolicity in wurtzite GaN

Comparing the imaginary part of the dielectric function of wurtzite GaN measured by spectroscopic ellipsometry at room temperature with calculations, we found the values of E p = ( 19.8 ± 0.5 ) eV , m 0 * = ( 0.201 ± 0.005 ) m 0 , and F = − 0.89 ± 0.05 for the momentum matrix element, electron effec...
