Two-step growth of (In,Ga)N pseudo-substrates on GaN templates by plasma-assisted molecular beam epitaxy
Huaide Zhang, Jingxuan Kang, Aidan F. Campbell +3
(In,Ga)N layers are grown by plasma-assisted molecular beam epitaxy on GaN templates. We introduce a two-step protocol that involves switching the growth conditions from initially…
Molecular Beam Epitaxy of AlScN Nanowires: Towards Group-III Nitride Piezoelectric Nanogenerators with Enhanced Response
Adriano Notarangelo, Rudeesun Songmuang, Mostafa Saleh +10
The paper reports the molecular beam epitaxy growth of Al₁₋ₓScₓN nanowires with controlled Sc content, integrates them into vertical piezoelectric nanogenerators, and demonstrates…
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…
Fabrication of (In,Ga)N pseudo-substrates by a three-step growth protocol without ex-situ processing
Huaide Zhang, Aidan F. Campbell, Jingxuan Kang +3
We fabricate (In,Ga)N pseudo-substrates with a total thickness of ~1 um grown on GaN templates using plasma-assisted molecular beam epitaxy. In a three-step process, we change grow…
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…
Combining metal dewetting and lateral etching for the scalable top-down fabrication of GaN nanowire arrays with independently tunable diameter and spacing
Jingxuan Kang, Rose-Mary Jose, Oliver Brandt +1
The top-down fabrication of nanowires based on patterning via metal dewetting is a cost-effective and scalable approach that is particularly suited for applications requiring large…
