Design of NbN superconducting nanowire single photon detectors with enhanced infrared photon detection efficiency
Qiang Wang, Jelmer J. Renema, Andreas Engel +1
We propose an optimized design for nanowire superconducting single photon detectors, using the recently discovered position dependent detection efficiency in these devices. This kn…
Characteristics of superconducting tungsten silicide WxSi1-x for single photon detection
X. Zhang, A. Engel, Q. Wang +7
Superconducting properties of three series of amorphous WxSi1-x films with different thickness and stoichiometry were investigated by dc transport measurements in a magnetic field…
Superconductivity in the ferromagnetic semiconductor SmN
E. -M. Anton, S. Granville, A. Engel +8
The discovery of materials that simultaneously host different phases of matter has often initially confounded, but ultimately enhanced, our basic understanding of the coexisting ty…
Position-Dependent Local Detection Efficiency in a Nanowire Superconducting Single-Photon Detector
Jelmer J. Renema, Qiang Wang, Rosalinda Gaudio +8
We probe the local detection efficiency in a nanowire superconducting single-photon detector along the cross-section of the wire with a spatial resolution of 10 nm. We experimental…
Detection Mechanism in SNSPD: Numerical Results of a Conceptually Simple, Yet Powerful Detection Model
Andreas Engel, Julia Lonsky, Xiaofu Zhang +1
In a recent publication we have proposed a numerical model that describes the detection process of optical photons in superconducting nanowire single-photon detectors (SNSPD). Here…
Numerical analysis of detection-mechanism models of SNSPD
Andreas Engel, Andreas Schilling
The microscopic mechanism of photon detection in superconducting nanowire single-photon detectors is still under debate. We present a simple, but powerful theoretical model that al…
