Research: Thermoelectrics

CURRENT RESEARCH
Development of sustainable materials for thermoelectrics.

GOAL
To use nanotechnology to improve the thermoelectric properties of materials, with a particular focus on ­readily available and sustainable materials:

  • Nanostructured silicon and silicon compounds for temperatures of 600°C and above
  • Nanostructured oxides for temperatures up to 600°C and above
  • Molecularly composed p- and n-type metal chalcogenides (M2E3, M = Sb, Bi; E = Se, Te) and skutterudites (Co3Sb) for temperatures up to 250°C
  • Nanocrystalline diamond, as its large bandgap makes it well suited for applications at temperatures above >600°C which is of particular interest as a model system

HIGHLIGHTS

  • Realization of the entire process chain, from synthesis of the material to development of test demonstration models
  • 2014 North Rhine-Westphalia Innovation Award for the development of thermoelectric generators made from nanostructured silicon (awarded to Dr.-Ing. Gabi Schierning)
  • 2012 InnoMateria Award for the first thermoelectric generator made from nano-silicon (UDE, IUTA, SLV)
