Excitonic condensation under spin-orbit coupling and BEC-BCS crossover
(The American Physical Society, 2007)
The condensation of electron-hole pairs is studied at zero temperature and in the presence of a weak spin-orbit coupling (SOC) in coupled quantum wells. Under realistic conditions, a perturbative SOC can have observable ...
Theoretical investigation of the effect of sample properties on the electron velocity in quantum Hall bars
(The American Physical Society, 2007)
We report on our theoretical investigation of the effects of the confining potential profile and sample size on the electron velocity distribution in (narrow) quantum Hall systems. The electrostatic properties of the ...
Analysis of skewed X-chromosome inactivation in females with rheumatoid arthritis and autoimmune thyroid diseases
(BioMed Central, 2009)
Introduction The majority of autoimmune diseases such as rheumatoid arthritis (RA) and autoimmune thyroid diseases (AITDs) are characterized by a striking female predominance superimposed on a predisposing genetic background. ...
Electrical conduction properties of Si δ-doped GaAs grown by MBE
(2009)
The temperature dependent Hall effect and resistivity measurements of Si δ-doped GaAs are performed in a temperature range of 25-300 K. The temperature dependence of carrier concentration shows a characteristic minimum at ...
A self-consistent microscopic model of Coulomb interaction in a bilayer system as an origin of Drag Effect Phenomenon
(Elsevier B.V., 2008)
In this work we implement the self-consistent Thomas-Fermi model that also incorporates a local conductivity model to an electron-electron bilayer system, in order to describe novel magneto-transport properties such as the ...
Raman and TEM studies of Ge nanocrystal formation in SiOx: Ge/SiOx multilayers
(Wiley, 2007)
Alternating germanosilicate-siliconoxide layers of 10-30 nm thickness were grown on Si substrates by plasma enhanced chemically vapor deposition (PECVD). The compositions of the grown films were determined by X-ray ...
Experimental and theoretical investigations of electronic and atomic structure of Si-nanocrystals formed in sapphire by ion implantation
(IOP, 2008)
The semiconductor nanocomposites based on Si nanocrystals in dielectric matrices attract a great amount of attention due to their ability for luminescence in visible and near-IR part of the electromagnetic spectrum. Si ...
Pulse shaping for a long-distance optical synchronization system
(Denshi Jouhou Tsuushin Gakkai, Institute of Electronics Information and Communication Engineer, 2007)
Next generation free electron lasers aim to generate x-ray pulses with pulse durations down to 30 fs, and possibly even sub-fs. Synchronization of various stages of the accelerator and the probe laser system to the x-ray ...
Atomistic structure simulation of silicon nanocrystals driven with suboxide penalty energies
(American Scientific Publishers, 2008)
The structural control of silicon nanocrystals embedded in amorphous oxide is currently an important technological problem. In this work, an approach is presented to simulate the structural behavior of silicon nanocrystals ...
Coupling and phase analysis of cavity structures in two-dimensional photonic crystals
(American Physical Society, 2005)
An experimental and numerical study of the coupling properties of cavity waveguides and the phase advancement through the coupled cavity waveguides in two-dimensional photonic crystals is presented. We find
that the ...
