Large-scale solution-phase production of Bi₂Te₃ and PbTe nanowires using Te nanowire templates.

Abstract

We report the first demonstration of large scale (>10 g) and high yield (>80%) production of ultrathin (<15 nm) PbTe and Bi₂Te₃ nanowires in a low-cost solution-based process using Te nanowire templates. The PbTe or Bi₂Te₃ nanowires can be compressed into high relative density disks with nanoscale grains.
