Using light and heat to controllably switch and reset disorder configuration in nanoscale devices
A. M. See, M. Aagesen, P. E. Lindelof +2
Quantum dots exhibit reproducible conductance fluctuations at low temperatures due to electron quantum interference. The sensitivity of these fluctuations to the underlying disorde…
The role of background impurities in the single particle relaxation lifetime of a two-dimensional electron gas
S. J. MacLeod, K. Chan, T. P. Martin +5
We re-examine the quantum tau_q and transport tau_t scattering lifetimes due to background impurities in two-dimensional systems. We show that the well-known logarithmic divergence…
Gate-dependent tunneling-induced level shifts observed in carbon nanotube quantum dots
J. V. Holm, H. I. Jørgensen, K. Grove-Rasmussen +3
We have studied electron transport in clean single-walled carbon nanotube quantum dots. Because of the large number of Coulomb blockade diamonds simultaneously showing both shell s…
Dilation of the Giant Vortex State in a Mesoscopic Superconducting Loop
S. Pedersen, G. R. Kofod, J. C. Hollingbery +2
We have experimentally investigated the magnetisation of a mesoscopic aluminum loop at temperatures well below the superconducting transition temperature . The flux quantisa…
Weak localisation in AlGaAs/GaAs p-type quantum wells
S. Pedersen, C. B. Sorensen, A. Kristensen +3
We have for the first time experimentally investigated the weak localisation magnetoresistance in a AlGaAs/GaAs p-type quantum well. The peculiarity of such systems is that spin-or…
Temperature dependence of the ``0.7'' 2(e^2)/h quasi plateau in strongly confined quantum point contacts
A. Kristensen, P. E. Lindelof, J. B. Jensen +8
We present new results of the ``0.7'' 2(e^2)/h structure or quasi plateau in some of the most strongly confined point contacts so far reported. This strong confinement is obtained…
