Towards low-dimensional hole systems in Be-doped GaAs nanowires
A. R. Ullah, J. G. Gluschke, P. Krogstrup +3
GaAs was central to the development of quantum devices but is rarely used for nanowire-based quantum devices with InAs, InSb and SiGe instead taking the leading role. p-type GaAs n…
Advances in the theory of III-V Nanowire Growth Dynamics
Peter Krogstrup, Henrik I. Jørgensen, Erik Johnson +6
Nanowire (NW) crystal growth via the vapour_liquid_solid mechanism is a complex dynamic process involving interactions between many atoms of various thermodynamic states. With incr…
Mesoscopic conductance fluctuations in InAs nanowire-based SNS junctions
T. S. Jespersen, M. L. Polianski, C. B. Soerensen +2
We report a systematic experimental study of mesoscopic conductance fluctuations in superconductor/normal/superconductor (SNS) devices Nb/InAs-nanowire/Nb. These fluctuations far e…
Kondo-Enhanced Andreev Tunneling in InAs Nanowire Quantum Dots
T. Sand-Jespersen, J. Paaske, B. M. Andersen +7
We report measurements of the nonlinear conductance of InAs nanowire quantum dots coupled to superconducting leads. We observe a clear alternation between odd and even occupation o…
Different quantization mechanisms in single-electron pumps driven by surface acoustic waves
P. Utko, K. Gloos, J. Bindslev Hansen +2
We have studied the acoustoelectric current in single-electron pumps driven by surface acoustic waves. We have found that in certain parameter ranges two different sets of quantize…
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…
