Analysis of Nb3Sn surface layers for superconducting RF cavity applications
Chaoyue Becker, Samuel Posen, Nickolas Groll +7
We present an analysis of the Nb3Sn surface layers grown on a bulk niobium (Nb) coupon prepared at the same time and by the same vapor diffusion process used to make Nb3Sn coatings…
Tunneling spectroscopy of superconducting MoN and NbTiN grown by atomic layer deposition
Nickolas Groll, Jeffrey A. Klug, Chaoyue Cao +6
A tunneling spectroscopy study is presented of superconducting MoN and NbTiN thin films grown by atomic layer deposition (ALD). The films exhibited a superconductin…
Heteroepitaxy of Group IV-VI Nitrides by Atomic Layer Deposition
Jeffrey A. Klug, Nicholas G. Becker, Nickolas R. Groll +5
Heteroepitaxial growth of selected group IV-VI nitrides on various orientations of sapphire (α-Al2O3) is demonstrated using atomic layer deposition. High quality, epitaxial films a…
Effect of high temperature heat treatments on the quality factor of a large-grain superconducting radio-frequency niobium cavity
P. Dhakal, G. Ciovati, G. R. Myneni +10
Large-grain Nb has become a viable alternative to fine-grain Nb for the fabrication of superconducting radio-frequency cavities. In this contribution we report the results from a h…
Tunable multi-photon Rabi oscillations in an electronic spin system
S. Bertaina, N. Groll, L. Chen +1
We report on multi-photon Rabi oscillations and controlled tuning of a multi-level system at room temperature (S=5/2 for Mn2+:MgO) in and out of a quasi-harmonic level configuratio…
Entrapment of magnetic micro-crystals for on-chip electron spin resonance studies
N. Groll, S. Bertaina, M. Pati +2
On-chip Electron Spin Resonance (ESR) of magnetic molecules requires the ability to precisely position nanosized samples in antinodes of the electro-magnetic field for maximal magn…
