Finite Element Simulations on Scaling Effects of 3D SiGe Thermoelectric Generators

  • Nicholas Williams (a1), Ali Gokirmak (a1) and Helena Silva (a1)

We report 3D finite element simulations analyzing scaling effects on the performance of single Silicon Germanium thermoelectric generator with 170 μm tall metal contacts. Temperature dependent material parameters are included to accurately model device performance. Power density was extracted for a range of widths, heights, and operating temperature. Depending upon cross sectional area of the SiGe leg and operating temperature, height can be optimized for maximum power density.
