03/24 - SnSe has a light-induced electronic phase transition
Congratulations Ben Dringoli!
In this paper we show the record-setting thermoelectric material SnSe has a light-induced phase transition, corresponding to a band gap collapse. Our measurements indicate a sudden heterogeneous nucleation of this new phase at a critical excitation fluence. This new phase is not thermally accessible, and may possess interesting new properties that we are currently exploring.
