Direct and indirect capture of carriers into the lasing ground state and the light-current characteristic of quantum dot lasers
(Amer Inst Physics, 2014-03-14)
We calculate the light-current characteristic (LCC) of a quantum dot (QD) laser under the conditions of both direct and indirect capture of carriers from the optical confinement layer into the lasing ground state in QDs. ...
On initial enhancement of mesospheric dust associated plasma irregularities subsequent to radiowave heating
(Copernicus Publications, 2008)
Important observational manifestations of subvisible mesospheric dust are Polar Mesospheric Summer Echoes PMSE which are produced by scattering from electron irregularities produced by dust charging. It has been observed ...
Nonlinear second sound in solids
(American Physical Society, 1994-05-01)
We study the nonlinear propagation of thermal waves in rigid heat conductors using a model introduced by Ruggeri et al. We derive the lowest-order nonlinear corrections to the wave speed and show that the quadratic ...
Macroscopic properties of carbon nanotubes from molecular-mechanics simulations
(American Physical Society, 2004-06-01)
Results of molecular-mechanics simulations of axial and torsional deformations of a single wall carbon nanotube are used to find Young's modulus, the shear modulus, and the wall thickness of an equivalent continuum tube ...
An optimization framework to improve 4D-Var data assimilation system performance
(Academic Press Inc Elsevier Science, 2014-10-15)
A time-parallel approach to strong-constraint four-dimensional variational data assimilation
(Academic Press Inc Elsevier Science, 2016-05-15)
Structural properties and band offset determination of p-channel mixed As/Sb type-II staggered gap tunnel field-effect transistor structure
(AIP Publishing, 2012-09-01)
The structural properties and band offset determination of p-channel staggered gap In0.7Ga0.3As/GaAs0.35Sb0.65 heterostructure tunnel field-effect transistor (TFET) grown by molecular beam epitaxy (MBE) were investigated. ...
Buckling of multiwalled carbon nanotubes under axial compression
(American Physical Society, 2006-02-01)
Buckling of single-walled and multiwalled carbon nanotubes (SWNTs and MWNTs, respectively) due to axial compressive loads has been studied by molecular mechanics simulations, and results compared with those from the analysis ...
