Definitive Surface Magnetotransport Study of SmB
Yun Suk Eo, Steven Wolgast, Alexa Rakoski +11
After the theoretical prediction that SmB is a topological Kondo insulator, there has been an explosion of studies on the SmB surface. However, there is not yet an agreemen…
Conduction through subsurface cracks in bulk topological insulators
S. Wolgast, Y. S. Eo, Ç. Kurdak +2
Topological insulators (TIs) have the singular distinction of being electronic insulators while harboring metallic, conductive surfaces. In ordinary materials, defects such as crac…
Influence of Helical Spin Structure on the Magnetoresistance of an Ideal Topological Insulator
Teoman Ozturk, Richard L. Field, Yun Suk Eo +3
In an ideal topological insulator, the helical spin structure of surface electrons suppresses backscattering and thus can enhance surface conductivity. We investigate the effect of…
Hysteretic Magnetotransport in SmB6 at Low Magnetic Fields
Yun Suk Eo, Steven Wolgast, Teoman Ozturk +12
Utilizing Corbino disc structures, we have examined the magnetic field response of resistivity for the surface states of SmB6 on different crystalline surfaces at low temperatures.…
Magnetotransport Measurements of the Surface States of Samarium Hexaboride using Corbino Structures
Steven Wolgast, Yun Suk Eo, Teoman Ozturk +12
The recent conjecture of a topologically-protected surface state in SmB and the verification of robust surface conduction below 4 K have prompted a large effort to understand t…
Quantum oscillations in Kondo Insulator SmB
G. Li, Z. Xiang, F. Yu +15
In Kondo insulator samarium hexaboride SmB, strong correlation and band hybridization lead to an insulating gap and a diverging resistance at low temperature. The resistance di…
Low-temperature surface conduction in the Kondo insulator SmB
Steven Wolgast, Cagliyan Kurdak, Kai Sun +3
We study the transport properties of the Kondo insulator SmB with a specialized configuration designed to distinguish bulk-dominated conduction from surface-dominated conductio…
