Resistive signature of excitonic coupling in an electron-hole double layer with a middle barrier
Xingjun Wu, Wenkai Lou, Kai Chang +2
We study the interlayer scattering mediated by long-range Coulomb interaction between electrons (density n) and holes (p) in a double-layer system. The gated device is made of InAs…

Low-Temperature Conductivity of Weakly Interacting Quantum Spin Hall Edges in Strained-Layer InAs/GaInSb
Tingxin Li, Pengjie Wang, Gerard Sullivan +2
We report low-temperature transport measurements in strained InAs/Ga0.68In0.32Sb quantum wells, which supports time-reversal symmetry-protected helical edge states. The temperature…
