Formation and Microwave Losses of Hydrides in Superconducting Niobium Thin Films Resulting from Fluoride Chemical Processing
Carlos G. Torres-Castanedo, Dominic P. Goronzy, Thang Pham +18
Superconducting Nb thin films have recently attracted significant attention due to their utility for quantum information technologies. In the processing of Nb thin films, fluoride-…
Systematic Improvements in Transmon Qubit Coherence Enabled by Niobium Surface Encapsulation
Mustafa Bal, Akshay A. Murthy, Shaojiang Zhu +37
We present a novel transmon qubit fabrication technique that yields systematic improvements in T relaxation times. We fabricate devices using an encapsulation strategy that inv…
Characterization of Nb films for superconducting qubits using phase boundary measurements
Kevin M. Ryan, Carlos G. Torres-Castanedo, Dominic P. Goronzy +8
Continued advances in superconducting qubit performance require more detailed understandings of the many sources of decoherence. Within these devices, two-level systems arise due t…
Determination of band offsets of Ga2O3/FTO heterojunction for current spreading for high temperature and UV applications
Carlos G. Torres-Castanedo, Kuang-Hui Li, Xiaohang Li
Because of relatively low electron mobility of Ga2O3, it is important to identify proper current spreading materials. Fluorine-doped SnO2 (FTO) offers superior properties to those…
Conduction and valence band offsets of Ga2O3/h-BN heterojunction
Kuang-Hui Li, Carlos G. Torres-Castanedo, Suresh Sundaram +5
h-BN and Ga2O3 are two promising semiconductor materials. However, the band alignment of the Ga2O3/h-BN heterojunction has not been identified, hindering device development. In thi…
High-Temperature Photocurrent Mechanism of \b{eta}-Ga2O3 Based MSM Solar-Blind Photodetectors
B. R. Tak, Manjari Garg, Sheetal Dewan +5
High-temperature operation of metal-semiconductor-metal (MSM) UV photodetectors fabricated on pulsed laser deposited \b{eta}-Ga2O3 thin films has been investigated. These photodete…
