Abstract
Systematic study of optical properties of undoped and Fe-doped substrates grown by hydride vapor phase epitaxy has revealed a strong dependence of the photoluminescence, transmission, reflectivity and ellipsometric spectra on the Fe-doping level. The changes of the near-band-gap transmission, reflectivity and photoluminescence has been observed and ascribed to the absorption introduced by the density of states tails, and the Fe3+ -ions incorporated in the GaN-lattice. Several approaches towards quantifying the Fe-doping level are suggested.
Abstract (in Czech)
Systematické studium optických vlastností nedopovaných a železem dopovaných substrátů GaN odhalilo silnou závislost fotoluminiscenčních, transmisních, reflexních a elipsometrických spekter na úrovni legování. Změny transmise, reflexe a fotoluminiscence v blízkosti gapu byly připsány absorpci způsobené chvosty hustoty stavů a ionty Fe3+ zabudovanými do mříže GaN. Navrhujeme několik přístupů ke kvantifikaci úrovně legování.
