Fine Bi2Te3 wires fabricated by glass sealed melt spinning

Abstract

Applying a small size cooling system is essential to avoid thermal noise in the field of micro-electronics. Fine thermoelectric materials are required to construct the system. A glass sealed melt spinning process was attempted to fabricate the fine materials. Bi2Te 3 wires of 75 mum in diameter with oval cross section were successfully obtained. The original electrical resistivity and Seebeck coefficient of the wires were maintained after the process
