Fabrication of Macroporous Silicon in Organic Electrolytes and their Luminescence

Article Preview

Abstract:

The quasi-regular arrangements porous silicon was fabricated by by electrochemical process using organic solutions with front-side illumination, and SEM showed that the morphology of porous silicon was dependent sensitively on the current density, organic electrolytes and their concentration. The results indicate that N-dimethylformamide (DMF) is the best organic solution and quasi-regular arranged pores can be well organized in 20%HF/DMF solution. The luminescence shows fresh porous silicon can emit the red luminescence at room temperature and quench after nanoporous layer destroyed.
