Gate-defined quantum point contacts in a germanium quantum well
Han Gao, Zhen-Zhen Kong, Po Zhang +6
We report an experimental study of quantum point contacts defined in a high-quality strained germanium quantum well with layered electric gates. At zero magnetic field, we observe…

Triple Andreev dot chains in semiconductor nanowires
Hao Wu, Po Zhang, John P. T. Stenger +6
Kitaev chain is a theoretical model of a one-dimensional topological superconductor with Majorana zero modes at the two ends of the chain. With the goal of emulating this model, we…

Thermopower and Nernst measurements in a half-filled lowest Landau level
Xiaoxue Liu, Tingxin Li, Po Zhang +4
Motivated by recent proposal by Potter et al. [Phys. Rev. X 6, 031026 (2016)] concerning possible thermoelectric signatures of Dirac composite fermions, we perform a systematic exp…
