Raman, photoluminescence and optical absorption studies on nanocrystalline silicon
(2002)
Raman, photoluminescence (PL) and optical absorption results on silicon nanocrystals in SiO2 matrices prepared by RF sputtering method are presented. The samples have varying Si/SiO2 compositional fraction and are annealed ...
Porous Si formation and study of its structural and vibrational properties
(2002)
In situ current (I)–(V) voltage studies were carried out to get a better understanding of the mechanism of formation of porous silicon (PS). It is observed that on decreasing the anodization current density below a critical ...
