Nanoscale Gap-Plasmon-Enhanced Superconducting Photon Detectors at Single-Photon Level
(2023)
With a growing demand for detecting light at the single-photon level in various fields, researchers are focused on optimizing the performance of superconducting single-photon detectors (SSPDs) by using multiple approaches. ...
Developing a Next Generation Readout System for Microwave Kinetic Inductance Detectors
(Trinity College Dublin. School of Physics. Discipline of Physics, 2022)
Microwave Kinetic Inductance Detectors (MKIDs) are photon detectors based on superconducting resonators, capable of detecting single photons with inherent energy resolution and μs time resolution, while also allowing ...
Theoretical studies of carbon nanotubes interacting with magnetic atoms
(Trinity College (Dublin, Ireland). School of Physics, 2009)
The past twenty years have seen an enormous increase in interest in the properties
of low dimensional systems. Carbon nanotubes are an example of one such
system. They possess remarkable physical properties which it is ...
Thin solid films of closely-packed CdS nanocrystals as media for holographic grate writing
(World Scientific, 1997)
Improving the mechanical properties of graphene oxide based materials by covalent attachment of polymer chains
(2013)
We report on the modification of graphene oxide (GO) with polyvinylalcohol (PVA) leading to the mechanical improvement of GO based materials. First, GO was covalently functionalised with PVA by esterification of carboxylic ...
Exfoliation of hematite: Morphological, structural and magnetic investigations
(2022)
Three natural specimens of hematite are characterized using X-ray diffraction, magnetometry, IR/Raman and Mössbauer spectroscopy, with focus on the Morin transition. All are exfoliated by grinding and prolonged sonication ...
Coulomb Calligraphy
(2023)
The equilibrium configurations of N Coulomb charges confined by a harmonic potential in two dimensions are found to exhibit a wide variety of patterns that are pleasing to the eye, when adjacent points are joined up. We ...
Density-functional study of Fe3AL: LSDA versus GGA
(American Physical Society, 2002)
The local-spin-density approximation and the generalized-gradient approximation ~GGA! are used to perform
density-functional total-energy calculations at zero temperature for Fe3Al in the ordered D03 and L12
structures. ...
Tunable phonon-induced steady state coherence in a double-quantum-dot charge qubit
(2020)
Charge qubits can be created and manipulated in solid-state double-quantum-dot (DQD) platforms. Typically, these systems are strongly affected by quantum noise stemming from coupling to substrate phonons. This is usually ...
The zero-moment half metal: How could it change spin electronics?
(2016)
The Heusler compound Mn2RuxGa (MRG) may well be the first compensated half metal. Here, the structural, magnetic and transport properties of thin films of MRG are discussed. There is evidence of half-metallicity up to x = ...
