Many-body effects in a quasi-one-dimensional electron gas

Sanjeev Kumar, Kalarikad J. Thomas, Luke W. Smith +6

We have investigated electron transport in a quasi-one dimensional (quasi-1D) electron gas as a function of the confinement potential. At a particular potential configuration, and…

Multiplexed Charge-locking Device for Large Arrays of Quantum Devices

R. K. Puddy, L. W Smith, H. Al-Taie +7

We present a method of forming and controlling large arrays of gate-defined quantum devices. The method uses a novel, on-chip, multiplexed charge-locking system and helps to overco…

Hierarchy of modes in an interacting system

O. Tsyplyatyev, A. J. Schofield, Y. Jin +7

Studying interacting fermions in 1D at high energy, we find a hierarchy in the spectral weights of the excitations theoretically and we observe evidence for second-level excitation…

Direct Imaging of Coherent Quantum Transport in Graphene Heterojunctions

E. D. Herbschleb, R. K. Puddy, P. Marconcini +5

We fabricate a graphene p-n-p heterojunction and exploit the coherence of weakly-confined Dirac quasiparticles to resolve the underlying scattering potential using low temperature…

Density-dependent thermopower oscillations in mesoscopic two-dimensional electron gases

Vijay Narayan, Eugene Kogan, Chris Ford +6

We present thermopower and resistance measurements on GaAs-based mesoscopic two-dimensional electron gases (2DEGs) as functions of the electron density . At high …

Statistical study of conductance properties in one-dimensional quantum wires focussing on the 0.7 anomaly

L. W. Smith, H. Al-Taie, F. Sfigakis +9

The properties of conductance in one-dimensional (1D) quantum wires are statistically investigated using an array of 256 lithographically-identical split gates, fabricated on a GaA…
