Abstract

We report on the electrochemical deposition of carbon-coated porous silicon composite films. PSi samples were fabricated via laterally-configured anodization cell set-up varying the applied current density. Carbon layer was coated through thermolysis of a polyfurfuryl alcohol (PFA) precursor on PSi surface. SEM micrographs show that the PSi film fabricated from a higher current density contained a thicker carbon layer. Raman spectra show peaks centered at ~1360cm^-1 and ~1600cm^-1 which corresponds to the D and G bands of carbon. Reflectance spectroscopy was done to examine the optical changes of PSi and carbon-coated PSi composite films. The interference fringes visible at the spectra of PSi films were reduced after coating that may be attributed from the high absorption of the deposited carbon layer.
