Electrochemical deposition of Bi-Te alloy films from acidic solutions containing Bi(NO[sub 3])[sub 3] and TeO[sub 2] has been investigated. The thickness, compound, and composition of the Bi-Te alloy films have been examined using stylus-type surface profiling techniques, X-ray diffraction peak measurement, and inductively coupled plasma/Auger electron spectroscopy measurements. At potentials where limiting current was observed, the compositions of films were controlled by the mole ratio [Bi[sup 3+]]/[HTeO[sup +][sub 2]] in the solutions and the relationship between the composition of electrodeposited films and the composition of electrolyte solutions was derived.
