The SWAP EUV Imaging Telescope Part I: Instrument Overview and Pre-Flight Testing
(2013)
The Sun Watcher with Active Pixels and Image Processing (SWAP) is an EUV solar telescope on board ESA?s Project for Onboard Autonomy 2 (PROBA2) mission launched on 2 November 2009. SWAP has a spectral band- pass centered ...
Deterministic multi-level spin orbit torque switching using focused He+ ion beam irradiation
(2023)
He+ ion irradiation is used to pattern multiple areas of Pt/Co/W films with different irradiation doses in Hall bars. The resulting perpendicular magnetic anisotropy landscape enables selective multilevel current-induced ...
Confined optical modes and amplified spontaneous emission from a microtube cavity formed by vacumm assisted filtration
(American Physical Society, 2006)
The authors demonstrate a new route to the fabrication of individual aluminosilicate microtubes that can act as micron-scale optical cylindrical resonators. The microtubes were prepared using a simple vacuum assisted wetting ...
Enhancing the electrical properties of MoS2 through nonradiative energy transfer
(2017)
In this study highly efficient nonradiative energy transfer from semiconductor quantum dots to monolayer MoS 2 with an efficiency of ~99% is demonstrated. Although the energy transfer efficiency is close to unity, there ...
Determination of the PIn antisite structure in InP by optically detected electron-nuclear double resonance
(American Physical Society, 1987)
Optically detected electron-nuclear double resonance (ODENDOR) is reported for the PIn antisite in p-type InP. In both electron-irradiated and as-grown samples, ENDOR signals from the four nearest P neighbors and the next ...
Friedel Oscillations in graphene: Sublattice Asymmetry in Doping
(2013)
Symmetry breaking perturbations in an electronically conducting medium are known to produce Friedel oscillations in various physical quantities of an otherwise pristine material. Here we show in a mathematically transparent ...
Theoretical modelling of physiologically stretched vessel in magnetisable stent assisted magnetic drug targeting application
(2010)
The magnetisable stent assisted magnetic targeted drug delivery system in a physiologically stretched vessel is considered theoretically. The changes in the mechanical behaviour of the vessel are analysed under the influence ...
Ab initio study of electron transport in dry poly(G)-poly(C) A-DNA strands
(2010)
The bias-dependent transport properties of short poly (G)-poly(C) A-DNA strands attached to Au electrodes are investigated with first-principles electronic-transport methods. By using the nonequilibrium Green's function ...
Ultrafast Double Pulse All-Optical Reswitching of a Ferrimagnet
(2021)
All-optical reswitching has been investigated in the half-metallic Heusler ferrimagnet Mn2Ru0.9Ga, where Mn atoms occupy two inequivalent sites in the XA-type structure. The effect of a second 200 fs, 800 nm laser pulse ...
