Rectified Voltage Induced by a Microwave Field in a Confined Two-Dimensional Electron Gas with a Mesoscopic Static Vortex
D. Schmeltzer, Hsuan-Yeh Chang
We investigate the effect of a microwave field on a confined two dimensional electron gas which contains an insulating region comparable to the Fermi wavelength. The insulating reg…

The Non-Dissipative Spin-Hall Current
D. Schmeltzer
A theory based on the Aharonov -Bohm effect in the momentum space for the Spin-Hall conductivity without a magnetic field is presented. The two dimensional Rashba Hamiltonian is di…
