TLDR
In this article, reproducible fabrication of InP−InAsP nanowire light-emitting diodes in which electron−hole recombination is restricted to a quantum-dot-sized InAsP section is reported.Abstract:
We report reproducible fabrication of InP−InAsP nanowire light-emitting diodes in which electron−hole recombination is restricted to a quantum-dot-sized InAsP section. The nanowire geometry naturally self-aligns the quantum dot with the n-InP and p-InP ends of the wire, making these devices promising candidates for electrically driven quantum optics experiments. We have investigated the operation of these nanoLEDs with a consistent series of experiments at room temperature and at 10 K, demonstrating the potential of this system for single photon applications.read more

TL;DR: It is shown that the crystal structure of indium phosphide (InP) nanowires can be controlled by using impurity dopants, and it is demonstrated that zinc decreases the activation barrier for two-dimensional nucleation growth of zinc-blende InP and therefore promotes crystallization of the InPnanowires in the zinc- Blende, instead of the commonly found wurtzite, crystal structure.

Spin–orbit qubit in a semiconductor nanowire
TL;DR: In this paper, a spin-orbit quantum bit (qubit) is implemented in an indium arsenide nanowire, where the spinorbit interaction is so strong that spin and motion can no longer be separated.
