Thermoelectric transport in topological insulator Bi2Te2Se bulk crystals
Materials Research Society Symposium Proceedings
Bi 2 Te 2 Se (BTS221) bulk crystals were recently discovered as an intrinsic 3D topological insulator. We have synthesized this material, and studied the transport properties of BTS221 from the thermoelectrics perspective. Temperature (T) dependent resistivity measurement indicates surface dominant transports in our sample at low T. We also report Seebeck measurement between 50K to room T.doi:10.1557/opl.2013.938 fatcat:hxp6jb7ylbcm5ebszr6gnm5r24
