抜粋

ZnTe thin films were electrochemically deposited onto Au-coated Cu substrates from an electrolytic solution containing ZnSO 4, TeO 2, citric acid and sodium citrate. Effects of deposition potentials and solution's Zn concentrations on the structure, chemical composition and electrical property were investigated. The resistivity, conduction type, carrier density, and carrier mobility were evaluated with a Hall effect measurement apparatus. A film with nearly stoichiometric composition was deposited at - 0.80 V vs. Ag /AgCl at 353 K from a solution containing 2.0 × 10 -2 kmol m -3-ZnSO 4, 1.0 × 10 -4 kmol m -3-TeO 2, 9.0 × 10 -2 kmol m -3-citric acid and 2.1 × 10 -1 kmol m -3-sodium citrate and was well crystallized with cubic preferential orientation along the (111) plane. A resistivity, the carrier density and the carrier mobility were 4.1 × 10 2 Ωm, 2.9 × 10 19 m -3 and 5.3 × 10 -4 m 2 V-1 s -1, respectively.
