Defect-Free Axially-Stacked GaAs/GaAsP Nanowire Quantum Dots with Strong Carrier Confinement
Yunyan Zhang, Anton V. Velichko, H. Aruni Fonseka +7
Axially-stacked quantum dots (QDs) in nanowires (NWs) have important applications in fabricating nanoscale quantum devices and lasers. Although their performances are very sensitiv…
Towards Ultra-Low-NoiseMoAu Transition Edge Sensors
D. J. Goldie, A. V. Velichko, D. M. Glowacka +1
We report initial measurements on our firstMoAu Transition Edge Sensors (TESs). The TESs formed from a bilayer of 40 nm of Mo and 106 nm of Au showed transition temperatures of abo…
On the determination of the quasiparticle scattering rate in unconventional superconductors by microwave surface impedance
N. T. Cherpak, A. A. Barannik, R. Prozorov +2
In the approximation of validity of the Drude expression for quasiparticle conductivity and the assumption that all electrons at T = 0 transform into a superfluide condensate, the…
On the microwave response of thin superconducting films with trapped magnetic flux
D A Luzhbin
Basing on the phenomenological model of the microwave response of thin superconducting films with trapped magnetic flux elaborated in Luzhbin et al (2005) Supercond. Sci. Technol.…
Nonlinear Dielectric Microwave Losses in MgO Substrates
M. A. Hein, D. E. Oates, P. J. Hirst +2
We have investigated the nonlinear surface impedance and two-tone intermodulation distortion of nine epitaxial YBa2Cu3O7-d films on MgO substrates, using stripline resonators, at f…
Anomalous Nonlinear Microwave Response of Epitaxial YBa2Cu3O7-x Films on MgO
M. A. Hein, P. J. Hirst, R. G. Humphreys +2
We have investigated the anomalous nonlinear microwave response of epitaxial electron-beam coevaporated YBa2Cu3O7-x films on MgO. The power and temperature dependent surface impeda…
