Paper Abstract

Thin Sn films in the thickness range 0.3-2nm are deposited by r.f.-sputtering on porous silicon (PS) anodized on p-type silicon. Microstructural features of the samples before and after r.f.-tin-sputtered are investigated with scanning electron microscopy (SEM). The photoluminescence (PL) studies showed that a broad luminescence peak of PS near the 621nm region gets a reduction in intensity, and a new peak at 441nm was produced at first and then disappeared. The FTIR spectra on the PS/Sn structure revealed no major change of the native PS peaks.
