Band Gap Determination from Photoconductivity Excitation Spectra
https://doi.org/10.47612/0514-7506-2022-89-3-405-409
Abstract
The possibility to determine the direct and indirect band gap from photoconductivity spectrum is shown. Using various structures as an example, it is shown, that the band gap determined from the photoconductivity spectrum differs from the one determined from the edge optical spectrum. By this method in composite structures it is possible to indicate impurity band gaps.
