The Evolution of Quasiparticle Charge in the Fractional Quantum Hall Regime
T. G. Griffiths, E. Comforti, M. Heiblum +2
The charge of quasiparticles in a fractional quantum Hall (FQH) liquid, tunneling through a partly reflecting constriction with transmission t, was determined via shot noise measur…
Observation of a Fifth of the Electron Charge
M. Reznikov, R. de Picciotto, T. G. Griffiths +2
We report the observation of quasi-particles with a charge q=e/5 detected by shot noise measurements in the 2/5 conducting channel (filling factor 2/5). This is in agreement with p…
Metal-insulator transition at B=0 in an ultra-low density () two dimensional GaAs/AlGaAs hole gas
M. Y. Simmons, A. R. Hamilton, T. G. Griffiths +3
We have observed a metal-insulator transition in an ultra-low density two dimensional hole gas formed in a high quality GaAs-AlGaAs heterostructure at B=0. At the highest carrier d…
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…
