Popis: | GaNxAs1−x samples with × ranging from 0.043% to 2.8% were grown by MOVPE. Analysing low-temperature photoluminescence spectra taken under hydrostatic pressure and room temperature photomodulated reflectance spectra gives strong evidence that the transition from N acting as an isoelectronic impurity to forming N-induced bands takes place at a N-concentration of about 0.2%. |
