Direct observation of surface state thermal oscillation in SmB6 oscillators
Brian Casas, Alex Stern, Dmitry K. Efimkin +2
SmB6 is a mixed valence Kondo insulator that exhibits a sharp increase in resistance following an activated behavior that levels off and saturates below 4K. This behavior can be ex…
Kondo insulator SmB6 under strain: surface dominated conduction near room temperature
A. Stern, M. Dzero, V. M. Galitski +2
SmB6 is a strongly correlated mixed-valence Kondo insulator with a newly discovered surface state, proposed to be of non-trivial topological origin. However, the surface state domi…
Radio Frequency Tunable Oscillator Device Based on SmB6 Microcrystal
A. Stern, D. K. Efimkin, V. Galitski +2
Radio frequency tunable oscillators are vital electronic components for signal generation, characterization, and processing. They are often constructed with a resonant circuit and…
