H. Ghoumaribouanani et al., PHASE-EQUILIBRIA IN A COPPER TELLURIDE PL US BISMUTH TELLURIDE SYSTEM, Materials research bulletin, 28(9), 1993, pp. 901-908
The phase diagram of the binary Cu2Te-Bi2Te3 system was determined by
x-ray and DTA measurements. In a first time the successive phase trans
itions of the Cu2Te composition have been confirmed as well as its str
uctural modifications as a function of the temperature. As the result,
it has been shown that the terminal Bi2Te3 based solid solution is no
nexistent. The electronic doping character of the copper atoms is emph
asised and some electric transport properties have been measured.
