Spin-current-induced electric field

Spin polarization and dichroism effects induced by an electric field

We show that electric field can induce spin polarization and dichroism effects in angle resolved photoemission spectroscopy ARPES in spin orbit coupling systems. The physical origin behind the effects essentially is the same as the intrinsic spin Hall effect induced by the electric field. Since the ARPES experiments have both energy and momentum resolutions, the origin of the intrinsic spin Hal...

Electric field induced nuclear spin resonance mediated by oscillating electron spin domains in GaAs-based semiconductors.

We demonstrate an alternative nuclear spin resonance using a radio frequency (rf) electric field [nuclear electric resonance (NER)] instead of a magnetic field. The NER is based on the electronic control of electron spins forming a domain structure. The rf electric field applied to a gate excites spatial oscillations of the domain walls and thus temporal oscillations of the hyperfine field to n...

Electric Field and Strain Effects on Surface Roughness Induced Spin Relaxation in Silicon Field-Effect Transistors

The potential of reduction of power consumption and the growth of computational speed achieved by scaling of semiconductor devices is close to exhaustion. Utilizing spin properties of electrons might provide an opportunity for further improvement of the properties of microelectronic-based devices. Since silicon is the main material currently used in microelectronics, we investigate the properti...

Axial current generation from electric field: chiral electric separation effect.

We study a relativistic plasma containing charged chiral fermions in an external electric field. We show that with the presence of both vector and axial charge densities, the electric field can induce an axial current along its direction and thus cause chirality separation. We call it the chiral electric separation effect (CESE). On a very general basis, we argue that the strength of CESE is pr...
