Magnetic Characteristics of Sunspot Groups and their Role in Producing Adverse Space Weather
(Trinity College Dublin. School of Physics. Discipline of Physics, 2019)
The energy that powers solar flares is known to come from magnetic energy stored in sunspot groups, but the precise conditions required and processes involved in energy release remain unclear. The likelihood of ...
Small-signal analysis of 1.3/spl mu/m microcavity light-emitting diodes
(1999)
THE MODULATION SPEED OF 1.3-MU M MICROCAVITY LIGHT-EMITTING DIODES (MCLED'S) HAS BEEN MEASURED USING A SMALL-SIGNAL MODULATION ANALYSIS, A SPEED OF 260 MHZ USING A 25-MU M DIAMETER SAMPLE AT CURRENT DENSITY OF 10 KA/CM(2) ...
Interaction of surface plasmons with CdTe quantum dot excitons
(SPIE, 2005)
A 5-fold enhancement in the luminescence of CdTe nanocrystal quantum dots (QDs) is observed when they are placed in
proximity to a nanostructured Au film deposited by pulsed laser deposition technique. No enhancement is ...
Exchange-biased magnetic tunnel junctions with antiferromagnetic epsilon-Mn3Ga
(2012)
Oriented c-axis films of the hexagonal triangular antiferromagnetic ?-Mn3Ga have been used in bottom-pinned synthetic antiferromagnetmagnetic tunnel junctions with MgO barriers, which show up to 150% tunneling magnetoresistance ...
Transition from the Exhibition to the Non-exhibition of Negative Differential Thermal Resistance in the Two-segment Frenkel-Kontorova Model
(2009)
An extensive study of the one-dimensional two-segment Frenkel-Kontorova (FK) model reveals a transition from the counterintuitive existence to the ordinary nonexistence of a negative-differential-thermal-resistance (NDTR) ...
Resonating modes of vibrating microcantilevers in liquid
(2008)
A study of nanomechanical cantilevers vibrating at various resonating modes in liquid is presented. Resonant frequency spectrum with 16 well resolved flexural modes is obtained. The quality factor increased from 1 at mode ...
Selective electrochemical production of hydrogen peroxide at zigzag edges of exfoliated molybdenum telluride nanoflakes
(2020)
The two-electron reduction of molecular oxygen represents an effective strategy to enable the green, mild and on-demand synthesis of hydrogen peroxide. Its practical viability, however, hinges on the development of advanced ...
Magnetization profile of magnetic impurities in graphene nanoribbons
(2011)
The magnetic properties of graphene-related materials, and in particular, the spin-polarized edge states predicted for pristine graphene nanoribbons (GNRs) with certain edge geometries have received much attention recently ...
Crystallographic Characterisation of Ultra-Thin, or Amorphous Transparent Conducting Oxides ? The Case for Raman Spectroscopy
(2020)
The electronic and optical properties of transparent conducting oxides (TCOs) are closely linked to their crystallographic structure on a macroscopic (grain sizes) and microscopic (bond structure) level. With the increasing ...
