Investigation of low voltage Fabry-Perot modulators for optical interconnect applications
(Trinity College (Dublin, Ireland). School of Physics, 2001)
Optical interconnect technology is one of the proposed solutions to the fast approaching communication bottleneck in electronic digital systems, arising from the bandwidth limitations of electrical interconnects. Optical ...
Antiband instability on vicinal Si(111) under the condition of diffusion-limited sublimation
(2012)
In this paper, we investigate the antiband instability on vicinal Si(111) surfaces with different angles of misorientation. It is known that prolonged direct current-annealing of Si(111) results in the formation of antibands; ...
Near-infrared dye having a large ultrafast third-order susceptibility
(1986)
Efficient degenerate four-wave mixing of 160-psec infrared light pulses at ? = 1.064 ?m in solutions of a new dye that absorbs between 1.0 and 1.6 ?m is reported. A Kerr-like third-order susceptibility of X(3)xyyx = 8 ? ...
The growth of high-crystalline quality M n 2 Au (110) thin films
(2022)
Mn2Au is a bimetallic antiferromagnetic with an extraordinarily high Néel temperature of 1600 K. Mn2Au has also been found to demonstrate Néel-order spin–orbit torque, allowing for electrical switching of the antiferromagnetic ...
Current trends in amorphous magnetism
(IEEE, 1984)
Recent research on some topics in amorphous magnetism is reviewed and questions are posed which should be answered by future work. The topics are i) appearance of magnetism in binary alloys of the 3d transition elements ...
Structural, magnetic and electronic properties of L21 -ordered Ru2-xMn1+xAl Heusler alloy thin films
(2023)
The cubic Heusler alloy Ru2–xMn1+xAl is grown in thin film form on MgO and MgAl2O4 substrates. It is a
highly spin-polarised ferrimagnetic metal, with weak magnetocrystalline anisotropy. Although structurally and
chemically ...
Covalently functionalized hexagonal boron nitride nanosheets by nitrene addition
(Wiley, 2012)
Exfoliated h-BN nanosheets were covalently functionalized via a one-step nitrene addition using azide precursor molecules. Functionalized h-BN nanosheets were found to exhibit markedly enhanced dispersability relative to ...
All-optical synchronization and multiplication of the frequency of mode-locked signals
(IEEE, 1993)
We report all-optical synchronized multiplication
by rational fractions of the modulation frequency of optical
signals in self-pulsing two-section semiconductor laser diodes.
The effect is based on the overlap of harmonics ...
Superparamagnetism in MgO-based magnetic tunnel junctions with a thin pinned ferromagnetic electrode
(2010)
MgO-based magnetic tunnel junctions have been fabricated with a thin Co40Fe40B20 (CoFeB) layer in the pinned synthetic antiferromagnetic CoFe/Ru/CoFeB stack. An inverted tunneling magnetoresistance is observed due to the ...
Quantifying the Piezoresistive Mechanism in High-Performance Printed Graphene Strain Sensors
(2022)
: Printed strain sensors will be important in applications such as
wearable devices, which monitor breathing and heart function. Such sensors need to
combine high sensitivity and low resistance with other factors such ...
