摘要：

Bismuth telluride alloys-Bi0.5Sb1.5Te3 and Bi1.8Sb0.2Te3.33Se0.17-have been deposited on polycrystalline zirconia via solidification under centrifugal pressure. The crystal growth under centrifugal pressure was a process in which the starting powders charged in the groove patterns of the substrates were first melted and then solidified under centrifugal acceleration of 10(4) m/s(2). This new process offers c-axis-oriented films with a thickness of more than 100 mu m. A mirror-like surface is another characteristic feature of these films. Owing to their orientation, reasonable power factors such as 4.2 mW/m K-2 and 2.7 mW/m K-2 (in plane) were obtained for p- and n-type films, respectively.
