Low temperature characterization of modulation doped SiGe grown on bonded silicon-on-insulator [PDF]

open access: yes, 1996
Modulation doped pseudomorphic Si0.87Ge0.13 strained quantum wells were grown on bonded silicon-on-insulator (SOI) substrates. Comparison with similar structures grown on bulk Si(100) wafers shows that the SOI material has higher mobility at low ...

Modeling climate influences on male survival in the highly polygynous southern elephant seal (Mirounga leonina)

open access: yesEcosphere, Volume 15, Issue 6, June 2024.
Abstract The Southern Ocean, its ecosystem, and inhabitants are vulnerable to climate‐mediated shifts in habitat conditions. These changes can affect marine predators in the long term through changes in the distribution, density, and quality of prey. To understand how these changes affect vital rates requires longitudinal studies integrating demography

Perceptions of Thai Aviation Students on Consumer Grade VR Flight Experiences

open access: yesProceedings, 2019
With extended reality (XR) technology on the rise in aviation education, we evaluated the perceptions of Thai students on an inexpensive and classroom-friendly virtual reality (VR) system and software combination, as an introduction to flying an aircraft.

Quantum interference and electron-electron interactions at strong spin-orbit coupling in disordered systems

open access: yes, 1998
Transport and thermodynamic properties of disordered conductors are considerably modified when the angle through which the electron spin precesses due to spin-orbit interaction (SOI) during the mean free time becomes significant.

Crossing-Line-Node Semimetals: General Theory and Application to Rare-Earth Trihydrides [PDF]

open access: yes, 2017
Multiple line nodes in energy-band gaps are found in semimetals preserving mirror-reflection symmetry. We classify possible configurations of multiple line nodes with crossing points (crossing line nodes) under point-group symmetry. Taking the spin-orbit

Spin transport of electrons through quantum wires with spatially-modulated strength of the Rashba spin-orbit interaction

open access: yes, 2004
We study ballistic transport of spin-polarized electrons through quantum wires in which the strength of the Rashba spin-orbit interaction (SOI) is spatially modulated.

Oscillating spin-orbit interaction as a source of spin-polarized wave packets in two-terminal nanoscale devices [PDF]

open access: yes, 2014
Ballistic transport through nanoscale devices with time-dependent Rashba-type spin-orbit interaction (SOI) can lead to spin-polarized wave packets that appear even for completely unpolarized input.

Spin-current quantization in a quantum point contact with spin-orbit interaction

open access: yes, 2010
We develop a realistic and analytically tractable model to describe the spin current which arises in a quantum point contact (QPC) with spin-orbit interaction (SOI) upon a small voltage is applied. In the model, the QPC is considered as a saddle point of

Quantum Phase Transitions of Light in the Dicke-Bose-Hubbard model [PDF]

open access: yes, 2007
We extend the idea of quantum phase transitions of light in atom-photon system with Dicke-Bose-Hubbard model for arbitrary number of two-level atoms. The formulations of eigenenergies, effective Rabi frequencies, and critical chemical potentials for two ...

Collapse of a tropical forest bird assemblage surrounding a hydroelectric reservoir

open access: yesGlobal Ecology and Conservation, 2018
Hydroelectricity is the world's largest source of ‘renewable’ energy, and deployment will expand considerably in the coming decade, with Asian countries installing the bulk of new generating capacity.
