Morphology, luminescence, and electrical resistance response to H2 and CO gas exposure of porous InP membranes prepared by electrochemistry in a neutral electrolyte
چکیده انگلیسی

Porous InP membranes have been prepared by anodization of InP wafers with electron concentration of 1 × 1017 cm−3 and 1 × 1018 cm−3 in a neutral NaCl electrolyte. The internal surfaces of pores in some membranes were modified by electrochemical deposition of gold in a pulsed voltage regime. Photoluminescence and photosensitivity measurements indicate efficient light trapping and porous surface passivation. The photoluminescence and electrical resistivity of the membranes are sensitive to the adsorption of H2 and CO gas molecules. These properties are also influenced by the deposition of Au nanoparticles inside the pores.
