本征半导体

The optically active defect centers of such types as E', two kinds of oxygen-deficiency and some kinds of oxygen-richness in silica play an important role in optical communication fiber and UV absorption. The researches on some oxygen-deficient defects and the metal ions doped or implanted semiconductor nanoparticles with fine luminescence properties have made it possible for silica to be used in the lighting field.

There is no obvious relation between temperature and semiconductor intrinsic properties. The passivation film represents the n-semiconductor characteristic in the potential interval of -0.5~0.1V, the p-semiconductor characteristic in the potential interval of 0.1~0.9V, and the n-semiconductor characteristic in the potential interval of

温度对于316L不锈钢钝化膜的半导体本征性质没有根本的影响：在-0.5~0.1V电位区间内钝化膜呈p型半导体特征；在0.1~0.9V电位区间内钝化膜呈n型半导体特征；在0.9~1.1V电位区间内钝化膜呈p型半导体特征。

Based on the project requirements, the research has focused on the confined electronic states in the semiconductor surface quantum wells. The moden quantum theory and advanced material growth technology have been used. The interband transitions in the surface quantum well have been studied by the in-situ photo-modulated reflection spectroscopy combined with the molecular beam epitaxy system. The optical transitions, including the tansition between ground or excited states of the electron and hole states, have been directly observed.
