Epitaxial aluminum contacts to InAs nanowires
N. L. B. Ziino, P. Krogstrup, M. H. Madsen +5
We report a method for making epitaxial superconducting contacts to semiconducting nanowires. The temperature and gate characteristics demonstrate barrier-free electrical contact,…
Direct Observation of Interface and Nanoscale Compositional Modulation in Ternary III-As Heterostructure Nanowires
Sriram Venkatesan, Morten H. Madsen, Herbert Schmid +3
Straight, axial InAs nanowire with multiple segments of GaInAs were grown. High resolution X-ray energy-dispersive spectroscopy (EDS) mapping reveal the distribution of group III a…
Single nanowire solar cells beyond the Shockley-Queisser limit
Peter Krogstrup, Henrik Ingerslev Jørgensen, Martin Heiss +5
Light management is of great importance to photovoltaic cells, as it determines the fraction of incident light entering the device. An optimal pn-junction combined with an optimal…
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…
