| 中文摘要 | when liquid phase epitaxy regrowth at 780 degrees c for 2 h is applied to the samples after molecular beam epitaxy, a decrease of the threshold current density in strained ingaas/gaas quantum well lasers by a factor of 3 to 4 is obtained. we suggest that this improvement is attributed to the reduction of nonradiative centers associated with deep levels at the three regions of the active region, the graded layer and the cladding layer. indeed, a significant reduction of deep center densities has been observed by using minority and majority carrier injection deep level transient spectroscopy measurements.
