    Prevention of gallium arsenide photocorrosion by an epoxy adhesion layer حسب Alqaradawi, Siham Y.

    منشور في 2004
    "…The room temperature electrical conductivity of the epoxy films increased from 10−8 to 10−4Ω−1cm−1 due to gold impregnation. Enhancement of the photocurrent due to gold impregnation is attributed due to better conduction of the photogenerated holes into the electrolyte, also due to activating the adsorption of electrolyte ions.Several parameters are studied with the objective of determining the stability of epoxy films: these are continuous current–voltage (I–E) scans, prolonged illumination, weight changes and surface topography by scanning electron microscopy. …"
