Nonlinear microwave photon-occupancy of a driven resonator strongly coupled to a transmon qubit
Baladitya Suri, Zach Keane, Lev S. Bishop +3
We measure photon-occupancy in a thin-film superconducting lumped element resonator coupled to a transmon qubit at 20mK and find a nonlinear dependence on the applied microwave…
Radio-frequency reflectometry on an undoped AlGaAs/GaAs single electron transistor
S. J. MacLeod, A. M. See, Z. K. Keane +5
Radio frequency reflectometry is demonstrated in a sub-micron undoped AlGaAs/GaAs device. Undoped single electron transistors (SETs) are attractive candidates to study single elect…
Universal Scaling of Nonequilibrium Transport in the Kondo Regime of Single Molecule Devices
G. D. Scott, Z. K. Keane, J. W. Ciszek +2
Scaling laws and universality are often associated with systems exhibiting emergent phenomena possessing a characteristic energy scale. We report nonequilibrium transport measureme…
Electronic and optical properties of electromigrated molecular junctions
D. R. Ward, G. D. Scott, Z. K. Keane +2
Electromigrated nanoscale junctions have proven very useful for studying electronic transport at the single-molecule scale. However, confirming that conduction is through precisely…
Three-terminal devices to examine single molecule conductance switching
Z. K. Keane, J. W. Ciszek, J. M. Tour +1
We report electronic transport measurements of single-molecule transistor devices incorporating bipyridyl-dinitro oligophenylene-ethynylene dithiol (BPDN-DT), a molecule known to e…
Magnetoresistance of atomic-scale electromigrated nickel nanocontacts
Z. K. Keane, L. H. Yu, D. Natelson
We report measurements of the electron transport through atomic-scale constrictions and tunnel junctions between ferromagnetic electrodes. Structures are fabricated using a combina…
Kondo resonances and anomalous gate dependence of electronic conduction in single-molecule transistors
L. H. Yu, Z. K. Keane, J. W. Ciszek +5
We report Kondo resonances in the conduction of single-molecule transistors based on transition metal coordination complexes. We find Kondo temperatures in excess of 50 K, comparab…
Inelastic electron tunneling via molecular vibrations in single-molecule transistors
L. H. Yu, Z. K. Keane, J. W. Ciszek +4
In single-molecule transistors, we observe inelastic cotunneling features that correspond energetically to vibrational excitations of the molecule, as determined by Raman and infra…
