Abstract

Read online

Performance of Si nanowires as thermoelectrics are evaluated only from cryogenic to ambient temperatures and ZT has remained low. Here, the authors systematically optimized the synthesis method and improved the suspended microdevice platform to achieve high-performance thermoelectrics up to 700 K.
