摘要: Cadmium selenide nanostructures have been electrodeposited on Ti substrate from aqueous acidic solution under high-energy conditions produced by pulse potential technique employing −300 V deposition and 50 µs width. The transport processes in non-steady state studied mathematical modelling the basis of diffusion equation. calculations confirmed that high-voltage electrodeposition operates very high energy localized close to electrode surface, limit CdSe formation zone was calculated be 1 µm cathode surface. It has demonstrated composition affects deposit morphology through its effect local current density near-electrode layer. X-ray diffraction analysis showed as-deposited had zinc blende crystalline structure changed hexagonal after annealing. Local elemental stoichiometric annealed deposits. optical band gap found 1.64 eV absorbance spectra.
