中文摘要 | we performed raman scattering investigations on low-temperature-grown (ltg) films of gaas that had been lifted off the gaas substrate. the raman measurements unambiguously show the effects of excess arsenic on phonon scattering from ltg films of gaas. the larger downwards shift of the lo phonon frequency for unannealed free-standing films is explained by invoking the elimination of mismatch strain. the raman signal due to precipitates of elemental arsenic in the annealed gaas : as films is determined. it is confirmed that the arsenic clusters formed by rapid thermal annealing are mainly amorphous, giving rise a broad raman peak in the range 180-260 cm(-1). |
