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. ...
Raman scattering in resonance with yellow luminescence transitions in GaN layers grown on sapphire by molecular beam epitaxy
(2000)
We have carried out defect-induced Raman scattering in resonance with yellow-luminescence (YL) transitions in GaN
layers grown on sapphire by electron cyclotron resonance-molecular beam epitaxy technique. The photoluminescence ...
Optical transitions and interface structure in (GaP)m/(AlP)n modulated period superlattices
(2004)
We have investigated optical transitions and atomically controlled interface structure in modulated period (GaP)m/(AlP)n (m, n number of monolayers) superlattices (SLs) using low-temperature photoluminescence (PL) and Raman ...
Surface morphology and formation of GaAs nanocrystals by laser-induced etching: SEM, PL and Raman studies
(2004)
GaAs nanostructures were prepared by a laser-induced etching process using a Nd:YAG (λ=1.06 μm) laser. Scanning electron microscope (SEM) was used to monitor changes in surface morphology produced on etching. The etched ...
