WebWhen a conducting layer is placed in a strong perpendicular magnetic field, there exist current-carrying electron states which are localized within approximately a cyclotron radius of the sample boundary but are extended around the perimeter of the sample. It is shown that these quasi-one-dimensional states remain extended and carry a current even in the …

WebThe dispersion of the plasma frequency of layered electron gases in GaAs-(AlGa) As heterostructures was determined by inelastic light scattering. The measured dispersions differ from that in two- and three-dimensional plasmas. They are linear in the in-plane component of the wave vector. This observation confirms predictions of theoretical models.

WebA display spectrometer is used to image the momentum distribution of photoelectrons from the Fermi level in graphite. The Fermi “surface” consists of six points at the corners K of the hexagonal, two-dimensional Brillouin zone, in agreement with band theory. The method is also applied to other equal energy surfaces below the Fermi level, thereby giving the band … WebMay 5, 2006 · The inverse process of the spin-Hall effect (ISHE), conversion of a spin current into an electric current, was observed at room temperature. A pure spin current was injected into a Pt thin film using spin pumping, and it was observed to generate electromotive force transverse to the spin current. By changing the spin-current polarization direction, the … WebNov 13, 2009 · [6] Williamson S J, Foner S and Dresselhaus M S 1965 Phys. Rev. 140 A1429.
