| 英文摘要 | Mn ions were doped into inas/gaas quantum dots samples by high energy. implantation and subsequent annealing. the optical and electric properties of the samples have been studied. the photoluminescence intensity of the samples annealed rapidly is stronger than that of the samples annealed for long time. by studying the relationship between the photoluminescence peaks and the implantation dose, it can be found that the photoluminescence peaks of the quantum dots show a blueshift firstly and then move to low energy with the implantation. dose increasing. the latter change in the photoluminescence peaks is probably attributed to that mn ions entering the inas quantum dots, which release the strain of the quantum dots. for the samples implanted by heavy dose (annealed rapidly) and the samples annealed for long time, the resistances versus temperature curves reveal anomalous peaks around 40 k. |
