Bi2Te3-based alloys are the best thermoelectric materials for near room temperature applications. However, its dimensionless figure of merit, ZT, has remained at a modest value of ~1 for the past 50 years. ZT is expected to increase in nanocomposite materials by maintaining a high power factor, but...
