Photoluminescence and Raman study of porous silicon synthesized by visible and infrared laser etching
(2001)
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
(2001)
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. ...
Nonlinear phenomenon in nanocrystallites produced by laser-induced etching of silicon
(2003)
Self-phase modulation of continuous wave argon-ion laser beam by a medium containing silicon nanocrystallites is reported here. Refractive index of nanocrystallites shows nonlinear behavior with the intensity of probing ...

Self-phase modulation of continuous wave argon-ion laser beam by a medium containing silicon nanocrystallites is reported here. Refractive index of nanocrystallites shows nonlinear behavior with the intensity of probing ...
Continuous wave laser-induced temperature rise in the thin films of silicon nanocrystals using Raman scattering
(2003)
Continuous wave (CW) laser-induced temperature rise is studied in Raman spectra of nanocrystalline-silicon (nC-Si) films on quartz and sapphire substrates. The zone-center-phonon (ZCP) mode in the Raman spectra shows ...
