Influence of Electrochemical Etching Parameters on Morphology of Porous Silicon

Abstract

In order to protect porous silicon from break and enhance it’s porosity and specific surface area, porous silicon is prepared with electrochemical etching method. The charateristic of porous silicon is investigated with SEM and high-speed adsorption surface area and porosity analyzer. The results show that the porous silicon prepared with the method of gradient etching and control of etching time is mechanically stable. The porosity and specfic surface area are improved.

Study on Performance of Silicon Ignitiors based on Energetic Chip of Porous Silicon

“…The porous silicon chips have micronano-scale precision and the microscale planar structure which greatly reduced the volume and the weight of initiator [3,4]. The performance of porous silicon energetic chip can be adjust by different concentration of NaClO4/methanol solution [5,6].…”
