Thermoelectricity in TmX2 based heterostructures

Thermoelectric refrigeration & Optimization of zT

Vibrations and maintenance-free clean cooling

Thermoelectric coolers for temperature
range - 50 to - 150 Co for:
infrared focal plane array detectors in a battle-field setting.
For cooling robotic and satellite systems. Cooling of ultrafast processors.

Challenges:
Both p and n-type materials of
high figure-of-merit (zT) are needed.
Bi85Sb15 is a good n-type material.
We need a p-type counterpart.

Theory:
Multiscale molecular
modeling, Machine
learning and ab initio
DFT and MD calculations
for optimization of σ, S and κ.
