Biochemical sensors based on polymer microrings with sharp asymmetrical resonance
(The American Institute of Physics, 2003-08-25)
Photonic microresonators have great potential in the application of highly sensitive sensors due to high Q-factor resonances and steep slopes between zero and unity transmission. A microring resonator with increased resonance ...
Nanoscale thermal transport
(The American Institute of Physics, 2003-01-15)
Rapid progress in the synthesis and processing of materials with structure on nanometer length scales has created a demand for greater scientific understanding of thermal transport in nanoscale devices, individual ...
Nature and distribution of electrically active defects in Si‐implanted and lamp‐annealed GaAs
(The American Institute of Physics, 1985-12-01)
The nature and spatial distribution of deep levels arising from defects in device‐quality, Si‐implanted, and lamp‐annealed liquid encapsulated Czochralski GaAs have been investigated. The best activation and mobility values ...
A model of flow and surfactant transport in an oscillatory alveolus partially filled with liquid
(The American Institute of Physics, 2005-03)
The flow and transport in an alveolus are of fundamental importance to partial liquid ventilation, surfactant transport, pulmonary drug administration, cell-cell signaling pathways, and gene therapy. We model the system ...
Monte Carlo studies on the well‐width dependence of carrier capture time in graded‐index separate confinement heterostructure quantum well laser structures
(The American Institute of Physics, 1993-10-04)
The total carrier capture time and the quantum well width are both important parameters affecting the graded‐index separate confinement heterostructure (GRINSCH) quantum well laser modulation speed limit. However, discrepancies ...
A Morphology-Cosmology Connection for X-Ray-Clusters
(Univ Chicago Press, 1993-12-10)
We employ N-body/three-dimensional gasdynamic simulations of the formation of galaxy clusters to determine whether cluster X-ray morpholgies can be used as cosmological constraints. Confirming the analytic expectations of ...
Magnetically modulated optical nanoprobes
(The American Institute of Physics, 2003-02-17)
We have developed magnetically modulated optical nanoprobes (MagMOONs) to magnetically modulate the signal from fluorescent probes and thus separate it from autofluorescence, electronic offsets, and other background signals. ...
Statistical Mechanics of Assemblies of Coupled Oscillators
(The American Institute of Physics, 1965-04)
It is shown that a system of coupled harmonic oscillators can be made a model of a heat bath. Thus a particle coupled harmonically to the bath and by an arbitrary force to a fixed center will (in an appropriate limit) ...
Conductivity of a system of metallic particles dispersed in an insulating medium
(The American Institute of Physics, 1973-06)
The variation of the conductivity of metal‐particle—insulator systems with the volume percent of metal is explained in terms of an ``effective medium'' theory.
Theory of photoluminescence in quantum wells in the presence of transverse electric field: Monte Carlo approach
(The American Institute of Physics, 1986-04-15)
The Monte Carlo approach is used to study the quasibound electron and hole ground‐state levels in a quantum well in the presence of a transverse electric field. A criteria is developed to ensure that the ground state is a ...
