Electrical and photoelectronic properties of hexagonal GaN

Photoconductivity of a non-intentionally doped GaN layer is observed for above band gap excitation. No below band gap excitation causes photoconductivity, but photoconductivity is optical quenched at energies of 1.28, 1.41, 1.53 and ≈2eV. The dark current and the yellow photoluminescence band show t...
