Examples
- The sem and the pl observation showed that the surface of porous silicon prepared by pulsed etching was more uniform and the si particles were smaller . the intensity of pl formed by pulsed etching method was enhanced and the peak had blue shift comparing that formed by dc electrochemical etching method . at the same time , it was observed that the smaller the dimension of the porous silicon , the broader energy gap of the porous silicon
采用脉冲和直流电化学腐蚀两种方法制备多孔硅，对这两种方法制备的多孔硅样品进行扫描电镜和荧光光谱的测量，发现脉冲腐蚀制备的多孔硅样品比直流腐蚀制备的多孔硅样品表面均匀、颗粒尺寸小、发光强度大，而且发光峰位有明显的蓝移现象。
