Single mode lasers based on slots suitable for photonic integration
(2011)
The re-growth free single mode lasers based on etched slots suitable for photonic integration are presented in this paper. The fabricated 650?m long laser exhibits a threshold current and a slope efficiency of about 32mA ...
Spin transport in higher n-acene molecules
(2011)
We investigate the spin-transport properties of molecules belonging to the acenes series by using density functional theory combined with the nonequilibrium Green's function approach to electronic transport. While short ...
Noncollinear ferrimagnetism and anomalous Hall effects in Mn4N thin films

and related ternary metallic perovskites with perpendicular anisotropy are interesting for spintronics, but their magnetic structures differ from the triangular ferrimagnetism of the bulk. A ...
Permanent magnet variable flux sources.
(IEEE, 1994)
Rotatable transversely-magnetized permanent magnet rods can be used to generate variable, uniform magnetic fields or field gradients. A four-rod device for use at the specimen stage of an optical microscope is described ...
Au4Mn: A localized ferromagnet with strong spin-orbit coupling, long-rangeferromagnetic exchange, and high Curie temperature
(2022)
Metallic Mn-based alloys with a nearest-neighbor Mn-Mn distance greater than 0.4 nm exhibit large, well-localized magnetic moments. Here we investigate the magnetism of tetragonal

Spin-flip inelastic electron tunneling spectroscopy in atomic chains
(2011)
We present a theoretical study of the spin transport properties of monoatomic magnetic chains with a focus on the spectroscopical features of the I - V curve associated with spin-flip processes. Our calculations are based ...
4D full-vector radio frequency complex magnetic susceptibility mapping. Near-field imaging of RFID tags
(2019)
Radio frequency identification (RFID) is a technology permeating both everyday life and scientific applications alike. The most prolific passive tag-based system uses inductively-powered tags with no internal power source ...
Influence of plasmonic array geometry on energy transfer from a quantum well to a quantum dot layer
(2016)
A range of seven different Ag plasmonic arrays formed using nanostructures of varying shape, size and gap were fabricated using helium-ion lithography (HIL) on an InGaN/GaN quantum well (QW) substrate. The influence of the ...
Highly emissive CdTe nanowires grown in a phosphate buffer solution: FLIM imaging and spectroscopic studies
(2007)
We present details on the formation and optical peroperties of CdTe nanowires, which were found to grow in a standard
phosphate-buffered solution, including micro-photoluminescence and fluorescence lifetime imaging.
