On The Ground State And Evolution Of Structural And Transport Properties Of Tin Selenide, Yufei Liu

All Dissertations

The recent surge of interest in tin selenide (SnSe) is due to the reported record-high thermoelectric figure of merit at elevated temperatures. While the researchers are exerting tremendous efforts to further improve the thermoelectric performance of SnSe via doping and nanostructuring, it is getting more and more apparent that SnSe is fascinating in many aspects of fundamental physics. SnSe is, in many aspects, an outlier of the current materials selection rules for high thermoelectric performance. Hence, answering why thermoelectric performance is high in SnSe should come before addressing how to further improve its thermoelectric performance. To this end, there are …
