自从发现多孔硅室温发射可见光现象以来,硅基纳米结构第Ⅳ族半导体发光研究引起了广泛关注。这不仅可以使传统的、成熟的硅平面工艺直接应用于光电器件中去,而且为介观系统新现象、新规律研究提供了一个理想的研究体系。由于SiO_2在硅集成电路中应
Since the discovery of visible-light emission from porous silicon at room temperature, the research of group IV semiconductors based on silicon-based nanostructures has drawn much attention. This not only enables the traditional and mature silicon planar technology to be applied directly to optoelectronic devices, but also provides an ideal research system for the study of new phenomena and phenomena in mesoscopic systems. Since SiO 2 should be in silicon integrated circuits
