Effects of a Parallel Magnetic Field on the Metal-Insulator Transition in a Dilute Two-Dimensional Electron System
Kevin Eng, X. G. Feng, Dragana Popovic +1
The temperature dependence of conductivity of a two-dimensional electron system in silicon has been studied in parallel magnetic fields B. At B=0, the system displays a meta…

Correlations between Aharonov-Bohm effects and one-dimensional subband populations in GaAs/AlGaAs rings
J. Liu, W. X. Gao, K. Ismail +3
The Aharonov-Bohm (AB) interference patterns in ring-shaped conductors are usually dominated by random features. The amplitude of the oscillations is random from sample to sample a…

Electron focusing, mode spectroscopy and mass enhancement in small GaAs/AlGaAs rings
J Liu, K Ismail, KY Lee +2
A new electron focusing effect has been discovered in small single and coupled GaAs/AlGaAs rings. The focusing in the single ring is attributed solely to internal orbits. The focus…
