Nanowire-based one-dimensional electronics
During the last half century, a dramatic downscaling of electronics has taken place, a miniaturization that the industry expects to continue for at least a decade. We present efforts to use theExpand

Verifying the Drude response
By now more than 100 years passed since Paul Drude suggested his highly acclaimed model of electronic transport. In the form advanced by A. Sommerfeld, the Drude model is still heavily utilized toExpand

Broadening of hot-spot response spectrum of superconducting NbN nanowire single-photon detector with reduced nitrogen content
The spectral detection efficiency and the dark count rate of superconducting nanowire single-photon detectors (SNSPD) have been studied systematically on detectors made from thin NbN films withExpand

Electrodynamics of the Superconducting State in Ultra-Thin Films at THz Frequencies
In this paper, we report on terahertz frequency-domain spectroscopy (THz-FDS) experiments in which we measure charge carrier dynamics and excitations of thin-film superconducting systems at lowExpand

Diameter-dependent conductance of InAs nanowires
Electrical conductance through InAs nanowires is relevant for electronic applications as well as for fundamental quantum experiments. Here, we employ nominally undoped, slightly tapered InAsExpand

Extremely slow Drude relaxation of correlated electrons
The electrical conduction of metals is governed by how freely mobile electrons can move throughout the material. This movement is hampered by scattering with other electrons, as well as withExpand

Observing electron spin resonance between 0.1 and 67 GHz at temperatures between 50 mK and 300 K using broadband metallic coplanar waveguides
We describe a fully broadband approach for electron spin resonance (ESR) experiments, where it is possible to tune not only the magnetic field but also the frequency continuously over wide ranges.Expand

Enhanced Cooper pairing versus suppressed phase coherence shaping the superconducting dome in coupled aluminum nanograins
Deterministic enhancement of the superconducting (SC) critical temperature $T_c$ is a long-standing goal in material science. One strategy is engineering a material at the nanometer scale such thatExpand

Anisotropic optical conductivity of the putative Kondo insulator CeRu4Sn6
Physics Department, University of Johannesburg, Auckland Park 2006, South Africa(Dated: September 14, 2012)Kondo insulators and in particular their non-cubic representatives have remained poorlyExpand

Single spin optically detected magnetic resonance with 60-90 GHz (E-band) microwave resonators.
Magnetic resonance with ensembles of electron spins is commonly performed around 10 GHz, but also at frequencies above 240 GHz and in corresponding magnetic fields of over 9 T. However, experimentsExpand
