Abstract: Photoluminescence of porous silicon at room temperature shifts to a larger wavelength in low-resistivity Si samples (0.006 OMEGA cm) when compared to the one emitted by high resistivity samples (0.4 OMEGA cm). This shift is associated with a coating of hydrocarbon over the porous silicon structure. The hydrocarbon coating was identified by electron energy loss spectroscopy imaging together with infrared spectroscopy.
