Unveiling the nucleation and growth of Zr oxide precipitates of internally oxidized Nb3Sn superconductors
Jaeyel Lee, Zugang Mao, Dieter Isheim +2
We report on atomic-scale analyses of nucleation and growth of Zr oxide precipitates and the microstructural evolution of internally oxidized Nb3Sn wires for high-field superconduc…
First Direct Observation of Nanometer size Hydride Precipitations on Superconducting Niobium
Zu Hawn Sung, Arely Cano, Akshay Murthy +5
Superconducting niobium serves as a key enabling material for superconducting radio frequency (SRF) technology as well as quantum computing devices. At room temperature, hydrogen c…
Selective thermal evolution of native oxide layer in Nb and Nb3Sn-coated SRF grade Nb: An in-situ angular XPS study
Arely Cano, Grigory V. Eremeev, Juan R. Zuazo +5
This contribution discusses the results of an in-situ angular XPS study on the thermal evolution of the native oxide layer on Nb3Sn and pure Nb. XPS data were recorded with convent…
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…
