Abstract
Spectrally resolved photoconductivity (PC) of p-type porous silicon (P S) samples was measured using a transparent liquid contact which ideal ly fills the pores. Lock-in detection of the photocurrent allows one t o separate the substrate and the porous layer signals by detecting pha se changes during the wavelength scan. The in-phase signal component w ith the substrate response characterizes the transmission of porous si licon, while the out-of-phase component is related to the actual PC of the PS film.
