Enhanced sputtering and incorporation of Mn in implanted GaAs and ZnO nanowires

A. Johannes, S. Noack, W. Paschoal +8

We simulated and experimentally investigated the sputter yield of ZnO and GaAs nanowires, which were implanted with energetic Mn ions at room temperature. The resulting thinning of…

Controlled growth of InAs nanowires on engineered substrates

Stefano Roddaro, Philippe Caroff, Giorgio Biasiol +8

We demonstrate the Au-assisted growth of semiconductor nanowires on different engineered substrates. Two relevant cases are investigated: GaAs/AlGaAs heterostructures capped by a $…

Measuring Temperature Gradients over Nanometer Length Scales

E. A. Hoffmann, H. A. Nilsson, J. E. Matthews +4

When a quantum dot is subjected to a thermal gradient, the temperature of electrons entering the dot can be determined from the dot's thermocurrent if the conductance spectrum and…

InAs Nanowire MOS Capacitors

Stefano Roddaro, Kristian Nilsson, Gvidas Astromskas +4

We present a capacitance-voltage study for arrays of vertical InAs nanowires. MOS capacitors are obtained by insulating the nanowires with a conformal 10nm HfO2 layer and using a t…

Quantum-dot thermometry

E. A. Hoffmann, N. Nakpathomkun, A. I. Persson +3

We present a method for the measurement of a temperature differential across a single quantum dot that has transmission resonances that are separated in energy by much more than th…

Fabrication, optical characterization and modeling of strained core-shell nanowires

Z. Zanolli, L. E. Froeberg, M. T. Bjoerk +2

Strained nanowires with varying InAs/InP core-shell thicknesses were grown using Chemical Beam Epitaxy. Microphotoluminescence spectroscopy, performed at low temperature, was then…
