Current flow past an etched barrier: field emission from a two-dimensional electron gas
D. H. Cobden, G. Pilling, R. Parthasarathy +5
We find that, under appropriate conditions, electrons can pass a barrier etched across a two dimensional electron gas (2DEG) by field emission from the GaAs/AlGaAs heterojunction i…
Experimental studies of T--shaped quantum dot transistors: phase-coherent electron transport
C. -T. Liang, J. E. F. Frost, M. Pepper +2
We have measured the low-temperature transport properties of a T-shaped quantum dot. Replicated oscillations superimposed on one-dimensional conductance steps are observed. These s…
Correlation Effects on the Coupled Plasmon Modes of a Double Quantum Well
N P R Hill, J. T. Nicholls, E. H. Linfield +5
At temperatures comparable to the Fermi temperature, we have measured a plasmon enhanced Coulomb drag in a GaAs/AlGaAs double quantum well electron system. This measurement provide…
Experimental evidence of a metal-insulator transition in a half-filled Landau level
C. -T. Liang, J. E. F. Frost, M. Y. Simmons +2
We have measured the low-temperature transport properties of a high-mobility front-gated GaAs/Al_{0.33}Ga_{0.67}As heterostructure. By changing the applied gate voltage, we can var…
Resonant transmission through an open quantum dot
C. -T. Liang, I. M. Castleton, J. E. F. Frost +5
We have measured the low-temperature transport properties of a quantum dot formed in a one-dimensional channel. In zero magnetic field this device shows quantized ballistic conduct…
