Microscopic origin of an exceptionally large phonon thermal Hall effect from charge puddles in a topological insulator
Rohit Sharma, Yongjian Wang, Yoichi Ando +2
We present the experimental observation of a drastically enhanced thermal Hall effect in the topological insulator material TlBiSbTe. Although heat transport…

Phonon thermal Hall effect in charge-compensated topological insulators
Rohit Sharma, Mahasweta Bagchi, Yongjian Wang +2
From a systematic study of thermal and charge transport in various single crystals of compensated topological insulators we identify the evolution of a large low-temperature therma…
