Rectification in mesoscopic AC-gated semiconductor devices
S. P. Giblin, M. Kataoka, J. D. Fletcher +6
We measure the rectified dc currents resulting when a 3-terminal semiconductor device with gate-dependent conductance is driven with an ac gate voltage. The rectified currents exhi…
Error detection in a tunable-barrier electron pump
S. P. Giblin, P. See, J. D. Fletcher +5
We measure the average number of electrons loaded into an electrostatically-defined quantum dot (QD) operated as a tunable-barrier electron pump, using a point-contact (PC) charge…
Observation of Coulomb blockade in nanostructured epitaxial bilayer graphene on SiC
Cassandra Chua, Arseniy Lartsev, Jinggao Sui +9
We study electron transport in nanostructures patterned in bilayer graphene patches grown epitaxially on SiC as a function of doping, magnetic field, and temperature. Away from cha…
Influence of impurity spin dynamics on quantum transport in epitaxial graphene
Samuel Lara-Avila, Sergey Kubatkin, Oleksiy Kashuba +6
Experimental evidence from both spin-valve and quantum transport measurements points towards unexpectedly fast spin relaxation in graphene. We report magnetotransport studies of ep…
Measurement and control of electron wave packets from a single-electron source
J. Waldie, P. See, V. Kashcheyevs +6
We report an experimental technique to measure and manipulate the arrival-time and energy distributions of electrons emitted from a semiconductor electron pump, operated as both a…
Hot carrier relaxation of Dirac fermions in bilayer epitaxial graphene
J. Huang, J. A. Alexander-Webber, T. J. B. M. Janssen +8
Energy relaxation of hot Dirac fermions in bilayer epitaxial graphene is experimentally investigated by magnetotransport measurements on Shubnikov-de Haas oscillations and weak loc…
