Nanoscale Thermoelectrics and Energy Harvesting in Nanowires

Surface and Interface Effects on Thermoelectric Behavior at the Nanoscale. Considerable research efforts have been devoted in recent years to understand how surface and interface transformations that change the shape, size, and microstructure of pure crystalline nanowires (NWs) in semiconductors can dramatically influence their thermoelectric properties, that is, their performance to convert waste heat into electricity at the nanoscale. In this research, using atomistic computer simulations, we are studying how special surface defects and interfaces, such as twin boundaries, can give rise to superior thermoelectric behavior in Si-based nanowires.
