Indium doping also affected the electronic properties. For the as-grown crystal (δ = 0), the band structure was the same as that of an intrinsic semiconductor, though that is a doped semiconductor due to the spontaneous doping effect.Therefore, the temperature dependence of the resistivity shows metallic behavior due to the holes injected at the top of the valence band by spontaneous doping.
