Tuneable electronic properties in graphene
M. F. Craciun, S. Russo, M. Yamamoto +1
Novel materials are in great demand for future applications. The discovery of graphene, a one atom thick carbon layer, holds the promise for unique device architectures and functio…
Exciton storage in a nano-scale Aharonov-Bohm ring with electric field tuning
Andrea M. Fischer, Vivaldo L. Campo, Mikhail E. Portnoi +1
We study analytically the optical properties of a simple model for an electron-hole pair on a ring subjected to perpendicular magnetic flux and in-plane electric field. We show how…
Quantum transport thermometry for electrons in graphene
K. Kechedzhi, D. W. Horsell, F. V. Tikhonenko +4
We propose a method of measuring the electron temperature in mesoscopic conductors and demonstrate experimentally its applicability to micron-size graphene devices in the lin…
Conductance of p-n-p graphene structures with 'air-bridge' top gates
R. V. Gorbachev, A. S. Mayorov, A. K. Savchenko +2
We have fabricated graphene devices with a top gate separated from the graphene layer by an air gap--a design which does not decrease the mobility of charge carriers under the gate…
Weak localisation in graphene flakes
F. V. Tikhonenko, D. W. Horsell, R. V. Gorbachev +1
We show that the manifestation of quantum interference in graphene is very different from that in conventional two-dimensional systems. Due to the chiral nature of charge carriers,…
Giant Fluctuations of Coulomb Drag in a Bilayer System
A. S. Price, A. K. Savchenko, B. N. Narozhny +2
We have observed reproducible fluctuations of the Coulomb drag, both as a function of magnetic field and electron concentration, which are a manifestation of quantum interference o…
