Simultaneously monitoring Ga adsorption and desorption kinetics on GaN(0001) using four in situ techniques
Huaide Zhang, Philipp John, Jingxuan Kang +3
We present a systematic investigation of Ga adsorption and desorption kinetics on the wurtzite GaN(0001) surface using four in situ techniques operated simultaneously: reflection h…
Dislocation correlations in GaN epitaxial films revealed by EBSD and XRD
Vladimir M. Kaganer, Domenik Spallek, Philipp John +2
Correlations between dislocations in crystals reduce the elastic energy via screening of the strain by the surrounding dislocations. We study the correlations of threading dislocat…
Growth of compositionally uniform layers with low relaxation degree on GaN by molecular beam epitaxy
Jingxuan Kang, Mikel Gómez Ruiz, Duc Van Dinh +7
500-nm-thick layers with 0.05-0.14 are grown using plasma-assisted molecular beam epitaxy, and their properties are assessed by a…
AlN Nanowire Based Vertically Integrated Piezoelectric Nanogenerators
N. Buatip, T. Auzelle, P. John +8
In this study, detailed analysis of the direct piezo-response of AlN nanowire-based vertically integrated nanogenerators (VINGs) is undertaken as a function of mechanical excitatio…
ScN/GaN(): a new platform for the epitaxy of twin-free metal-semiconductor heterostructures
Philipp John, Achim Trampert, Duc Van Dinh +6
We study the molecular beam epitaxy of rock-salt ScN on the wurtzite GaN() surface. To this end, ScN is grown on free-standing GaN() substrates and self-ass…
Composition and optical properties of (In,Ga)As nanowires grown by group-III-assisted molecular beam epitaxy
M Gómez Ruiz, Aron Castro, Jesús Herranz +5
(In,Ga) alloy droplets are used to catalyse the growth of (In,Ga)As nanowires by molecular beam epitaxy on Si(111) substrates. The composition, morphology and optical properties of…
