Journal ArticleDOI
Role of oxygen on microstructure and thermoelectric properties of silicon nanocomposites
Gabi Schierning,Ralf Theissmann,Niklas Stein,Nils Petermann,A. Becker,Markus Engenhorst,V. Kessler,Martin Geller,A. Beckel,Hartmut Wiggers,Roland Schmechel +10 more
TL;DR: In this article, the role of oxygen on microstructure and transport properties of the nanocomposite was investigated using a focused ion beam (FIB) and transmission electron microscopy (TEM).
Journal ArticleDOI
High Temperature Thermoelectric Device Concept Using Large Area PN Junctions
R. Chavez,Sebastian Angst,Joseph Hall,Joseph Hall,J. Stoetzel,V. Kessler,Lucas A. Bitzer,Franziska Maculewicz,Niels Benson,Hartmut Wiggers,Dietrich E. Wolf,Gabi Schierning,Roland Schmechel +12 more
TL;DR: In this paper, a high temperature thermoelectric device concept using large area nanostructured silicon p-type and n-type (PN) junctions is presented, where the electrical contacts are made at the cold side eliminating the hot side substrate and difficulties that go along with high temperature electrical contacts.
Journal ArticleDOI
Thermoelectric Properties of Nanocrystalline Silicon from a Scaled-Up Synthesis Plant†
V. Kessler,Devendraprakash Gautam,Tim Hülser,M. Spree,Ralf Theissmann,Markus Winterer,Hartmut Wiggers,Gabi Schierning,Roland Schmechel +8 more
TL;DR: In this article, the authors present the properties of thermoelectrics made from highly boron doped silicon nanoparticles, which are produced by a continuous gas phase process in a scaled-up synthesis plant enabling production rates in the kg'h−1 regime.
Journal ArticleDOI
Silicon‐based nanocomposites for thermoelectric application
Gabi Schierning,J. Stoetzel,R. Chavez,V. Kessler,Joseph Hall,Roland Schmechel,Tom Schneider,Nils Petermann,Hartmut Wiggers,Sebastian Angst,Dietrich E. Wolf,Benedikt Stoib,Anton Greppmair,Martin Stutzmann,Martin S. Brandt +14 more
TL;DR: In this paper, a gas phase synthesis for the nanoparticles is employed, which is capable of producing doped silicon (Si) nanoparticles, doped alloy nanoparticles of silicon and germanium (Ge), SixGe1-x, and doped composites of Si nanoparticles with embedded metal silicide precipitation phases.
Journal ArticleDOI
Fabrication of High-Temperature-Stable Thermoelectric Generator Modules Based on Nanocrystalline Silicon
V. Kessler,Martin Dehnen,R. Chavez,Markus Engenhorst,J. Stoetzel,Nils Petermann,K. Hesse,T. Huelser,M. Spree,Christian Stiewe,Pawel Ziolkowski,Gabi Schierning,Roland Schmechel +12 more
TL;DR: In this paper, high-temperature-stable thermoelectric generator modules (TGMs) based on nanocrystalline silicon have been fabricated, characterized by the Harman technique, and measured in a generator test facility at the German Aerospace Center.
