New Surface Treatment Technique of Porous Silicon
多孔硅新的表面处理技术

Using the anode oxidation surface treatment technique on PS introduced can efficiently avoid the PS to crack,shrink or collapse during the natural drying process. The anode oxidation surface treatment means to use a few negative ions to effect the PS surface,to clear up dangling bonds and to satisfy the chemical valence of Si molecules,so as to avoid the asymmetry inner stress between the molecules caused by restructure and to make the PS surface performance stable.Thus the PS with steady performance which can exist in the air for a long time can be prepared.
