SWT 2017 The Second Stuttgart Workshop on Thermoelectrics

On August 8, 2017, the 2nd Stuttgart Workshop on Thermoelectrics (SWT2) took place at the Institute for Materials Science of the University of Stuttgart. The follow-up event of last year’s SWT1 featured 20 oral and poster presentations and attracted more than 40 national and international participants from universities, research institutes and industry revealing the growing popularity of the conference. Topics span the whole range from basic research of common and novel materials through metrology to application. The workshop itself was framed by two tutorials given by Prof. Terry M. Tritt from Clemson University (USA), a worldwide leading authority in the field of thermoelectrics. The two lectures titled “Overview of Thermoelectric Phenomena and Applications & Selection  Criteria for Good Thermoelectric Materials” and “Bulk Thermoelectric Materials Measurements: A Look Behind the Curtain” offered valuable insights in the technology for both non-experts and specialists. Due to the growing success with the scientific community this conference format will be continued next summer.

The planned next workshop in this series SWT3 will take place in August 2018 and will broaden the topic to semiconductor basics and photovoltaic converters. Please enlist for further information on “phonons meet photons workshops” by sending an e-mail to Wenjie Xie (email).
