Fabrication Method for Thermoelectric Nanodevices

Abstract

Thermoelectric nanowire-based devices are fabricated by the electrodeposition of n-type Bi2Te3 and p-type BiSbTe nanowire bundles within the same alumina nanotemplate (see Figure). The nanowire bundles are approximately 50 μm in diameter and consist of nanowires 200 nm in diameter and 40 μm in length. These nanostructured materials could be used to create higher-efficiency power generation or cooling devices.
