Dislocation contrast in cathodoluminescence and electron-beam induced current maps on GaN(0001)
K. K. Sabelfeld, V. M. Kaganer, C. Pfüller +1
We theoretically analyze the contrast observed at the outcrop of a threading dislocation at the GaN(0001) surface in cathodoluminescence and electron-beam induced current maps. We…
Elastic vs. plastic strain relaxation in coalesced GaN nanowires: an x-ray diffraction study
Vladimir M. Kaganer, Bernd Jenichen, Oliver Brandt
The coalescence in dense arrays of spontaneously formed GaN nanowires proceeds by bundling: adjacent nanowires bend and merge at their top, thus reducing their surface energy at th…
Influence of strain relaxation in axial (In,Ga)N/GaN nanowire heterostructures on their electronic properties
Oliver Marquardt, Thilo Krause, Vladimir Kaganer +3
We present a systematic study of the influence of elastic strain relaxation on the built-in electrostatic potentials and the electronic properties of axial (In,Ga)N/GaN nanowire he…
