WebJan 15, 2010 · The spin Hall effect depends crucially on the intrinsic spin-orbit coupling of the energy band. Because of the smaller spin-orbit coupling in silicon, the spin Hall effect is expected to be much reduced. We show that the electric field in p-doped silicon can induce a dissipationless orbital current in a fashion reminiscent of the spin Hall effect. WebApr 10, 2024 · Hall effect states that when a current-carrying conductor is placed to a perpendicular magnetic field, the voltage can be identified at the right angle to the current. This process of obtaining a measurable voltage is called the hall effect. It is discovered by Edwin Herbert Hall in the year 1879. The applications of the Hall effect are following: WebHere, we report the observation of the fractional quantum Hall effect in a very low disorder InAs quantum well with a well width of 24 nm, containing a two-dimensional electron system with a ... fens way swanley
