Pulsed Electron Spin Resonance of an Organic Microcrystal by Dispersive Readout
Ailsa Keyser, Jonathan Burnett, Sergey Kubatkin +4
We establish a testbed system for the development of high-sensitivity Electron Spin Resonance (ESR) techniques for small samples at cryogenic temperatures. Our system consists of a…
Electron-phonon coupling of epigraphene at millikelvin temperatures
Bayan Karimi, Hans He, Yu-Cheng Chang +7
We investigate the basic charge and heat transport properties of charge neutral epigraphene at sub-kelvin temperatures, demonstrating nearly logarithmic dependence of electrical co…
Fast tunable high Q-factor superconducting microwave resonators
S. Mahashabde, E. Otto, D. Montemurro +3
We present fast tunable superconducting microwave resonators fabricated from planar NbN on a sapphire substrate. The wavelength resonators are tuning fork shaped and tuned b…
Two-level systems in superconducting quantum devices due to trapped quasiparticles
S. E. de Graaf, L. Faoro, L. B. Ioffe +6
A major issue for the implementation of large scale superconducting quantum circuits is the interaction with interfacial two-level system defects (TLS) that leads to qubit relaxati…
Ambipolar charge transport in quasi-free-standing monolayer graphene on SiC obtained by gold intercalation
Kyung Ho Kim, Hans He, Claudia Struzzi +6
We present a study of quasi-free-standing monolayer graphene obtained by intercalation of Au atoms at the interface between the carbon buffer layer (Bu-L) and the silicon-terminate…
The performance limits of epigraphene Hall sensors
Hans He, Naveen Shetty, Thilo Bauch +5
Epitaxial graphene on silicon carbide, or epigraphene, provides an excellent platform for Hall sensing devices in terms of both high electrical quality and scalability. However, th…
