Microwave photon-assisted phase-incoherent Cooper-pair tunneling in a Josephson STM
A. Roychowdhury, M. Dreyer, J. R. Anderson +2
We have observed photon-assisted Cooper-pair tunneling in an atomic-scale Josephson junction formed between a superconducting Nb tip and a superconducting Nb sample in a scanning t…

Plasma etching of superconducting Niobium tips for scanning tunneling microscopy
A. Roychowdhury, R. Dana, M. Dreyer +3
We report a reproducible technique for the fabrication of sharp superconducting Nb tips for scanning tunneling microscopy (STM) and scanning tunneling spectroscopy. Sections of Nb…

A 30 mK, 13.5 T scanning tunneling microscope with two independent tips
A. Roychowdhury, M. A. Gubrud, R. Dana +4
We describe the design, construction, and performance of an ultra-low temperature, high-field scanning tunneling microscope (STM) with two independent tips. The STM is mounted on a…
