Growth and Interface Engineering of Superconducting TiN on Sapphire by Thermal-Laser Epitaxy
Anthony Hyatt, Anand Ithepalli, Eegene Clara Chung +6
Thermal-laser epitaxy (TLE) extends the accessible pressure, temperature, and growth-rate regimes of conventional molecular-beam epitaxy, enabling in situ laser annealing, high-pur…
High-Q superconducting microwave resonators using MBE titanium nitride
Anand Ithepalli, Haoran Lu, Eegene Clara Chung +9
Using molecular beam epitaxy, we have realized thin films of titanium nitride (TiN) on c-plane sapphire that exhibit the lowest observed full-width at half maximum X-ray rocking cu…
Second-Order Optical Nonlinearity of AlScN Films Grown By Molecular Beam Epitaxy
Joongwon Lee, Thai-Son Nguyen, Len van Deurzen +8
Alloys of AlN have rapidly emerged as a material platform for nonlinear optics. In this paper, we measure the second-order optical nonlinearity of AlScN films grown directly on nit…
Loss Mechanisms in Cryogenic Microwave Epitaxial AlN Resonators
Hemant Gulupalli, Navnil Choudhury, Jiacheng Xie +6
Epitaxial aluminum nitride (AlN) thin-film bulk acoustic resonators (FBARs) enable low loss filtering for future 6G systems. They also provide a compact approach for qubit sensing…
Shubnikov-de Haas oscillations of two-dimensional electron gases in AlYN/GaN and AlScN/GaN heterostructures
Yu-Hsin Chen, Thai-Son Nguyen, Isabel Streicher +4
AlYN and AlScN have recently emerged as promising nitride materials that can be integrated with GaN to form two-dimensional electron gases (2DEGs) at heterojunctions. Electron tran…
