The role of Coulomb interaction in superconducting NbTiN thin films
D. Hazra, N. Tsavdaris, A. Mukhtarova +9
We report on the superconducting properties of NbTiN thin films of thickness 10 nm, with different Ti fraction in the range , deposited b…
Betatron resonance electron acceleration and generation of quasi-monoenergetic electron beams using 200fs Ti:Sapphire laser pulses
D. Hazra, A. Moorti, B. S. Rao +3
Generation of collimated, quasi-monoenergetic electron beams (peak energy ~17-22MeV, divergence ~10mrad, energy spread ~20%) by interaction of Ti:sapphire laser pulse of 200fs dura…
Quantum limited amplification from inelastic Cooper pair tunneling
S. Jebari, F. Blanchet, A. Grimm +7
Nature sets fundamental limits regarding how accurate the amplification of analog signals may be. For instance, a linear amplifier unavoidably adds some noise which amounts to half…
A self-aligned nano-fabrication process for vertical NbN-MgO-NbN Josephson junctions
A. Grimm, S. Jebari, D. Hazra +4
We present a new process for fabricating vertical NbN-MgO-NbN Josephson junctions using self-aligned silicon nitride spacers. It allows for a wide range of junction areas from 0.02…
