Journal ArticleDOI
Formation of a high quality two-dimensional electron gas on cleaved GaAs
Loren Pfeiffer,Ken W. West,Horst Stormer,J. P. Eisenstein,K. W. Baldwin,David Gershoni,J. Spector +6 more
TL;DR: In this article, a two-dimensional electron gas (2DEG) was fabricated on the cleaved (110) edge of a GaAs wafer by molecular beam epitaxy (MBE).
Journal ArticleDOI
Electron focusing in two‐dimensional systems by means of an electrostatic lens
TL;DR: In this article, an electrostatic lens for ballistic electrons in two-dimensional (2D) systems was introduced and demonstrated its focusing action in very high mobility GaAs•(AlGa)As heterostructures.
Journal ArticleDOI
Atomically precise superlattice potential imposed on a two-dimensional electron gas
TL;DR: In this paper, a two-dimensional electron gas containing an atomically precise, lateral Kronig-Penney potential of 102 A periodicity was fabricated by modulation-doped molecular beam epitaxy overgrowth on the cleaved edge of a 71 A GaAs/31 A AlGaAs compositional superlattice.
Journal ArticleDOI
Ballistic electron transport beyond 100 microm IN 2D electron systems
TL;DR: In this paper, the amplitude of the characteristic magneto-oscillations was found to depend exponentially on electron propagation distance with a decay length λ a = 15 microm.
Journal ArticleDOI
Refractive switch for two‐dimensional electrons
TL;DR: In this article, a refractive electrostatic prism is used to switch a beam of ballistic electrons between different collectors in the two-dimensional electron gas of an AlGaAs•GaAs heterostructure.
