Gate-activated photoresponse in a graphene p-n junction
M. C. Lemme, F. H. L. Koppens, A. L. Falk +4
We study photodetection in graphene near a local electrostatic gate, which enables active control of the potential landscape and carrier polarity. We find that a strong photorespon…
Gate-controlled Guiding of Electrons in Graphene
J. R. Williams, Tony Low, M. S. Lundstrom +1
Ballistic semiconductor structures have allowed the realization of optics-like phenomena in electronics, including magnetic focusing and lensing. An extension that appears unique t…
Coherent spin manipulation in an exchange-only qubit
E. A. Laird, J. M. Taylor, D. P. DiVincenzo +3
Initialization, manipulation, and measurement of a three-spin qubit are demonstrated using a few-electron triple quantum dot, where all operations can be driven by tuning the neare…
Dynamic Nuclear Polarization in the Fractional Quantum Hall Regime
A. Kou, D. T. McClure, C. M. Marcus +2
We investigate dynamic nuclear polarization in quantum point contacts (QPCs) in the integer and fractional quantum Hall regimes. Following the application of a dc bias, fractional…
Dynamic Nuclear Polarization in Double Quantum Dots
M. Gullans, J. J. Krich, J. M. Taylor +6
We theoretically investigate the controlled dynamic polarization of lattice nuclear spins in GaAs double quantum dots containing two electrons. Three regimes of long-term dynamics…
