Hysteretic magnetotransport in p-type AlxGa1-xAs heterostructures with In/Zn/Au ohmic contacts

B. Grbic, R. Leturcq, T. Ihn, K. Ensslin, G. Blatter, D. Reuter, A.D. Wieck

The two-terminal magneto-conductance of a hole gas in C-doped AlGaAs/GaAs heterostructures with ohmic contacts consisting of alloyed In/Zn/Au displays a pronounced hysteresis of the conductance around zero magnetic field. The hysteresis disappears above magnetic fields of around 0.5 T and…

Detecting single-electron tunneling involving virtual processes in real time

S. Gustavsson, M. Studer, R. Leturcq, T. Ihn, K. Ensslin, D.C. Driscoll, A.C. Gossard

We use time-resolved charge detection techniques to probe virtual tunneling processes in a double quantum dot. The process involves an energetically forbidden state separated by an energy δ from the Fermi energy in the leads. The non-zero tunneling probability can be interpreted as cotunneling,…

Monte Carlo modeling of carrier-carrier scattering in semiconductors with nonparabolic bands

Olivier Bonno, Jean-Luc Thobel

An efficient algorithm to account for nonparabolicity in carrier-carrier scattering in an ensemble Monte Carlo simulator is proposed. The major difficulty of modeling intercarrier scattering in semiconductors with nonparabolic bands arises from the two particle momentum and energy conservation laws…

Tight-binding description of the quasiparticle dispersion of graphite and few-layer graphene

A. Grüneis, Claudio Attaccalite, L. Wirtz, H. Shiozawa, R. Saito, T. Pichler, A. Rubio

A universal set of third–nearest neighbour tight–binding (TB) parameters is presented for calculation of the quasiparticle (QP) dispersion of N stacked sp2 graphene layers (N = 1 . . . ∞) with AB stacking sequence. The QP bands are strongly renormalized by electron–electron interactions which…
