中文摘要 | a systematic investigation on the photoluminescence (pl) properties of inxga1-xas/alyga1-xas (x = 0.15, y = 0, 0.33) strained quantum wells (sqws) with well widths from 1.7 to 11.0 nm has been performed at 77 k under high pressure up to 40 kbar. the experimental results show that the pressure coefficients of the exciton peaks corresponding to transitions from the first conduction subband to the heavy-hole subband increase from 10.05 mev/kbar of 11.0 nm well to 10.62 mev/kbar of 1.8 nm well for in0.15ga0.85as/gaas sqws. however, the corresponding pressure coefficients slightly decrease from 9.93 mev/kbar of 9.0 nm well to 9.73 mev/kbar of 1.7 nm well for in0.15ga0.85as/al0.33ga0.67as sqws. calculations based on the kronig-penney model reveal that the increased or decreased barrier heights and the increased effective masses with pressure are the main reasons of the change in the pressure coefficients. |
