多孔硅可见光发射现象是近一两年半导体物理学界的重大发现。1992年初,美国物理学会从1991年凝聚态物理和材料物理的80多项进展中选出七大进展,多孔硅可见光发射就是其中之一。多孔硅发光现象一出现,国际上一些权威刊物纷纷登载多孔硅的介绍文章,如英国《物理世界》先后有两期分别以“打开通向硅基光电子学之门”和“硅基光电子学走到尽头了吗?”为题报道和介绍这方面的进展情况。1991年4月,在美国材料学会的春季会议上,只有两篇有关多孔硅的文章,而在12月初的秋季会议上,多孔硅的研究报道增加到约60篇;今年举行的许多国际会议都有关于多孔硅的研
The phenomenon of porous silicon visible light emission is a major discovery in the field of semiconductor physics in recent one or two years. In early 1992, the American Physical Society selected seven major advances from more than 80 advances in condensed matter physics and material physics in 1991. Porous silicon visible light emission was one of them. Porous silicon luminescence phenomenon appears, some international authoritative publications have published articles on porous silicon, such as the British “physical world” has two phases, respectively, “to open the door to silicon optoelectronics” and “silicon Optoelectronics came to an end yet? ”Report and introduce progress in this area. In April 1991, at the spring meeting of the American Society of Materials, there were only two articles on porous silicon, and at the fall meeting in early December, the number of studies on porous silicon increased to about 60; many of the international conferences held this year There is research on porous silicon
