Visible Light Emission and Microplasma Phenomena in Silicon p–n Junction, I

抄録

Experimental results on the visible light emission and microplasma phenomena in silicon p–n junction are described. It has been found that the microplasma spot in the p–n junction can be located by scanning small chopped light spot on the junction surface. Combining this method of location of the microplasma spot and the observation by microscope, it is concluded that the light emitting spot does not necessarily coincide with the microplasma spot.
Possibility of the effect of impurities on the light-emitting phenomena is discussed briefly in connection with our recent experimental result on the visible light emission from germanium p–n junction. A simple model of p–n junction is proposed for the understanding of microplasma phenomenon.
