Spin-orbit interaction in InAs/GaSb heterostructures quantified by weak antilocalization
F. Herling, C. Morrison, C. S. Knox +5
We study the spin-orbit interaction (SOI) in InAs/ GaSb and InAs quantum wells. We show through temperature- and gate-dependent magnetotransport measurements of weak antilocalizati…
Enhanced shot noise in resonant tunnelling via interacting localised states
S. S. Safonov, A. K. Savchenko, D. A. Bagrets +4
In a variety of mesoscopic systems shot noise is seen to be suppressed in comparison with its Poisson value. In this work we observe a considerable enhancement of shot noise in the…
On the metallic behaviour in dilute two-dimensional systems
A. R. Hamilton, M. Y. Simmons, M. Pepper +1
We have studied the metallic behaviour in low density GaAs hole systems, and Si electron systems, close to the apparent two-dimensional metal-insulator transition. Two observations…
Weak localisation, hole-hole interactions and the "metal"-insulator transition in two dimensions
M. Y. Simmons, A. R. Hamilton, M. Pepper +4
A detailed investigation of the metallic behaviour in high quality GaAs-AlGaAs two dimensional hole systems reveals the presence of quantum corrections to the resistivity at low te…
Anomalous behaviour of S/N mesoscopic structures near T_c
S. Shapira, E. H. Linfield, C. J. Lambert +3
We observe a maximum in the conductance of Aluminum / n-GaAs junctions at temperatures 20 mK lower than the superconducting transition temperature. This is the first observation of…
Metal-insulator transition at B=0 in a dilute two dimensional GaAs-AlGaAs hole gas
M. Y. Simmons, A. R. Hamilton, M. Pepper +3
We report the observation of a metal insulator transition at B=0 in a high mobility two dimensional hole gas in a GaAs-AlGaAs heterostructure. A clear critical point separates the…
