... cmÀ2).Decay of PL intensity is a good indication of the stability of porous silicon particularly of the surface bond configurations [3,16].InFig. 4(A),decay of the PL intensity at the peak wave-length ... that the improved luminescent properties of our PSfilms is more an artifact of the substrate (texturedone) rather than that of the electrolyte alone. On the textured surface, the nucleation of ... the fabrication of porous silicon viz, HF, ethanol, H2O2andHNO3[1,11,12]. HF is mainly used for the dissolution of silicon, ethanol is basically used to reduce the surface tension of the...
