    Using the basic solution made of Bi(NO3)3· 5H2O(4.0 × 10-3, 4.5 × 10-3, 5.0 × 10-3, 6.0 × 10-3, 7.0 × 10 -3 kmol·m-3), TeO2: (3.0 × 10 -3 kmol.·m-3) and nitrilotriacetic acid (NTA: 0.1 kmol·m-3) at pH 9.5, electrochemical deposition of stoichiometric, crystalline Bi2Te3 film was carried out at various potential of -0.6, -0.7 and -0.8 V. The experimental results obtained are as follows; (1) Electrochemical experimental condition for crystalline Bi2Te3 film deposition is as follows: the basic solution containing Bi(No3)3·5H2O(5.0 × 10-3kmol·m-3), TeO2(3.0 × 10 -3kmol·m-3) and NTA(0.1 kmol·m-3) at pH 9.5 and deposition potential of -0.6V. (2) Various thermoelectric power properties such as semi-conductor type, electro-conductivity, Seebeck factor and power factor have been measured and evaluated for the crystalline Bi 2Te3 and other Bi-Te deposited films, as deposited and after heat-treated. It has been shown those properties of the heat-treated crystalline Bi2Te3 film has similar or superior thermo-electric properties with those made by MOCVD or a acidic solution process.
