Growth and characterization of single crystal cubic TaN and hexagonal TaN films on c-plane Sapphire
Anand Ithepalli, Amit Rohan Rajapurohita, Arjan Singh +7
Two single crystal phases of tantalum nitride were stabilized on c-plane sapphire using molecular beam epitaxy. The phases were identified to be -TaN with a rocksalt cubic struc…
Growth windows of epitaxial films on c-plane sapphire and their structural and superconducting properties
John G. Wright, Huili G. Xing, Debdeep Jena
NbN films are grown on c-plane sapphire substrates by molecular beam epitaxy. The structural and superconducting properties of the film are characterized to demonstrate that growth…
Ferroelectricity in Polar ScAlN/GaN Epitaxial Semiconductor Heterostructures
Joseph Casamento, Ved Gund, Hyunjea Lee +11
Room temperature ferroelectricity is observed in lattice-matched ~18% ScAlN/GaN heterostructures grown by molecular beam epitaxy on single-crystal GaN substrates. The epitaxial fil…
Momentum-resolved electronic band structure and offsets in an epitaxial NbN/GaN superconductor/semiconductor heterojunction
Tianlun Yu, John Wright, Guru Khalsa +9
The electronic structure of heterointerfaces play a pivotal role in their device functionality. Recently, highly crystalline ultrathin films of superconducting NbN have been integr…
An unexplored MBE growth mode reveals new properties of superconducting NbN
John Wright, Celesta Chang, Dacen Waters +8
Accessing unexplored conditions in crystal growth often reveals remarkable surprises and new regimes of physical behavior. In this work, performing molecular beam epitaxy of the te…
Epitaxial niobium nitride superconducting nanowire single-photon detectors
Risheng Cheng, John Wright, Huili G. Xing +2
Superconducting nanowires used in single-photon detectors have been realized on amorphous or poly-crystalline films. Here, we report the use of single-crystalline NbN thin films fo…
