Temperature Dependence of Spin-Split Peaks in Transverse Electron Focusing
Chengyu Yan, Sanjeev Kumar, Michael Pepper +5
We present experimental results of transverse electron-focusing measurements performed using n-type GaAs. In the presence of a small transverse magnetic field (B), electrons are fo…
Interference Effects in a Tunable Quantum Point Contact Integrated with an Electronic Cavity
Chengyu Yan, Sanjeev Kumar, Michael Pepper +5
We show experimentally how quantum interference can be produced using an integrated quantum system comprising an arch-shaped short quantum wire (or quantum point contact, QPC) of 1…
Direct observation of exchange-driven spin interactions in one-dimensional system
Chengyu Yan, Sanjeev Kumar, Kalarikad Thomas +6
We present experimental results of transverse electron focusing measurements performed on an n-type GaAs based mesoscopic device consisting of one-dimensional (1D) quantum wires as…
Fano Resonance in a cavity-reflector hybrid system
Chengyu Yan, Sanjeev Kumar, Michael Pepper +5
We present the results of transport measurements in a hybrid system consisting of an arch-shaped quantum point contact (QPC) and a reflector; together, they form an electronic cavi…
