Heat capacity of nichel sulfide and its semimetal-metal transition
(American Physical Society, 1974)
Heat-capacity measurements have been made from 5 to 330 K on NiS which shows a nonmetal-metal transition at 265 K, and on Ni0.95S which is metallic at all temperatures. The low-temperature data yield electronic specific-heat ...
Proximity-induced topological state in graphene
(2014)
The appearance of topologically protected states at the surface of an ordinary insulator is a rare occurrence and to date only a handful of materials are known for having this property. An intriguing question concerns the ...
Temperature tuning of two-photon absorption microcavity photodetectors for wavelength selective pulse monitoring
(2008)
Temperature tuning of a GaAs two-photon absorption microcavity
photodetector with a tuning rate of 0.125 nm per degree is demonstrated.
The detector response is shown to be independent of temperature
change in the range ...
Design of Low V-pi High-Speed GaAs Travelling-Wave Electrooptic Phase Modulators Using an n-i-p-n Structure
(2008)
GaAs-based electrooptic phase modulators using
an n-i-p-n structure and coplanar waveguide traveling-wave
electrodes are designed using the compact 2-D finite-difference
time-domain technique and Pade approximation ...
Conventional and inverse magnetocaloric effects in La(0.45)Sr(0.55)MnO(3) nanoparticles
(2011)
The magnetocaloric effect of La(0.45)Sr(0.55)MnO(3) nanoparticles was studied by dc magnetization measurements. A sample with mean particle size of about 140 nm exhibits both a conventional magnetocaloric effect around the ...
Supersymmetric noether currents and Seiberg-Witten theory
(Trinity College (Dublin, Ireland). School of Physics, 2000)
This thesis has been devoted to the construction of the Noether supercharges
for the Seiberg-Witten (SW) model. One of our most important results
is the first complete and direct derivation of the SW version of the ...
Machine-learning approach for quantified resolvability enhancement of low-dose STEM data
(2023)
High-resolution electron microscopy is achievable only when a high electron dose is employed, a practice that may cause damage to the specimen and, in general, affects the observation. This drawback sets some limitations ...
