Molecular Beam Epitaxy of AlScN Nanowires: Towards Group-III Nitride Piezoelectric Nanogenerators with Enhanced Response
Adriano Notarangelo, Rudeesun Songmuang, Mostafa Saleh +10
We study the molecular beam epitaxy of self-assembled AlScN nanowires on conductive TiN layers and demonstrate their application in piezoelectric na…
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…
Uniform large-area surface patterning achieved by metal dewetting for the top-down fabrication of GaN nanowire ensembles
Jingxuan Kang, Rose-Mary Jose, Miriam Oliva +6
The dewetting of thin Pt films on different surfaces is investigated as a means to provide the patterning for the top-down fabrication of GaN nanowire ensembles. The transformation…
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…
Growth kinetics and substrate stability during high-temperature molecular beam epitaxy of AlN nanowires
Philipp John, Mikel Gómez Ruiz, Len van Deurzen +5
We study the molecular beam epitaxy of AlN nanowires between 950 and 1215 °C, well above the usual growth temperatures, to identify optimal growth conditions. The nanowires are gro…
A route for the top-down fabrication of ordered ultrathin GaN nanowires
Miriam Oliva, Vladimir Kaganer, Maximilian Pudelski +5
Ultrathin GaN nanowires (NWs) are attractive to maximize surface effects and as building block in high-frequency transistors. Here, we introduce a facile route for the top-down fab…
Density control of GaN nanowires at the wafer scale using self-assembled SiN patches on sputtered TiN(111)
Thomas Auzelle, Miriam Oliva, Philipp John +3
The self-assembly of heteroepitaxial GaN nanowires using either molecular beam epitaxy (MBE) or metal-organic vapor phase epitaxy (MOVPE) mostly results in wafer-scale ensembles wi…
Interface recombination in Ga- and N-polar GaN/(Al,Ga)N quantum wells grown by molecular beam epitaxy
Thomas Auzelle, Chiara Sinito, Jonas Lähnemann +5
We explore and systematically compare the morphological, structural and optical properties of GaN/(Al,Ga)N multiple quantum wells (MQWs) grown by plasma-assisted molecular beam epi…
Self-assembly of well-separated AlN nanowires directly on sputtered metallic TiN films
Mani Azadmand, Tomas Auzelle, Jonas Lähnemann +7
We demonstrate the self-assembled formation of AlN nanowires by molecular beam epitaxy on sputtered TiN films on sapphire. This choice of substrate allows growth at an exceptionall…
Toward Quantitative Measurements of Piezoelectricity in III-N Semiconductors Nanowires
L. Jaloustre, S. Le-Denmat, T. Auzelle +4
Piezoelectric semiconductor III-Nitride nanostructures have received increasing interest as an alternative material for energy harvesters, sensors, and self-sustainable electronics…
