Abstract:
Properties of the electrochemically prepared porous III-V semiconductors, GaAs and InP, have been studied using scanning electron microscopy (SEM), atomic force microscopy (AFM), monochromatic multi-angle-of-incidence (MAI) ellipsometry, Raman scattering (RS), including confocal micro-Raman measurements. Two-layer oxide/porous structures have been observed for porous samples. The optical constants and filling factors of porous layers have been calculated in the frame of the effective medium approximation. The peculiarities of Raman spectra of porous GaAs and InP have been analyzed using the critical point analysis of the phonon dispersion.
