Bulk transport paths through defects in floating zone and Al flux grown SmB
Yun Suk Eo, Alexa Rakoski, Shriya Sinha +16
We investigate the roles of disorder on low-temperature transport in SmB crystals grown by both the Al flux and floating zone methods. We used the inverted resistance method wi…
Investigation of high-temperature bulk transport characteristics and skew scattering in samarium hexaboride
Alexa Rakoski, Yun Suk Eo, Çağlıyan Kurdak +3
A well-known feature in transport data of the topological Kondo insulator SmB is the sign change in the Hall coefficient at 65 K. Carriers in SmB are known to be negative,…
Robustness of the Insulating Bulk in the Topological Kondo Insulator SmB
Yun Suk Eo, Alexa Rakoski, Juniar Lucien +5
We used the inverted resistance method to extend the bulk resistivity of SmB to a regime where the surface conduction overwhelms the bulk. Remarkably, the bulk resistivity sh…
Understanding low-temperature bulk transport in samarium hexaboride without relying on in-gap bulk states
Alexa Rakoski, Yun Suk Eo, Kai Sun +1
We present a new model to explain the difference between the transport and spectroscopy gaps in samarium hexaboride (SmB), which has been a mystery for some time. We propose th…
