Photoluminescence and Raman study of porous silicon synthesized by visible and infrared laser etching
Visible and infrared lasers have been used to photochemically fabricate photoluminescent porous silicon thin films on n-type silicon substrates. Photoluminescence measurements on porous silicon exhibit a two-peak structure ...
Surface reconstruction of silicon and polysilicon by Nd:YAG laser etching: SEM, Raman and PL studies
A comparative study of porous silicon (PS) fabricated by laser-induced etching on n-type crystalline-silicon and n-type polysilicon substrates is presented here under near resonance conditions by employing a Nd:YAG laser. ...
