TOPICAL REVIEW: Semiconductor nanowires
(IOP Publishing Ltd, 2006-11-07)
Semiconductor nanowires (NWs) represent a unique system for exploring phenomena at the nanoscale and are also expected to play a critical role in future electronic and optoelectronic devices. Here we review recent advances ...
Electron energy states and miniband parameters in a class of non-uniform quantum well and superlattice structures
(Elsevier, 1985)
A simple method to compute the carrier energy states, miniband parameters and dispersion characteristics for single and multiple quantum well and superlattice structures is presented. The method utilizes the continuity of ...
Anisotropic Thermal Properties of Solid Polymers
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 2001-01)
This paper discusses the thermal conduction anisotropy in polymers by reviewing currently available theories and experimental methods for studying oriented polymers. The anisotropic thermal conductivity and diffusivity of ...
Raman spectroscopy of acoustic phonons in fibonacci superlattices
(Elsevier, 1987)
We report on resonant and non-resonant Raman scattering by acoustic phonons in Fibonacci GaAs---AlAs superlattices. Spectra off-resonance show doublets centered at frequencies that follow a power-law behavior, in good ...
Artificial economic life: a simple model of a stockmarket
(Elsevier, 1994-08-01)
We describe a model of a stockmarket in which independent adaptive agents can buy and sell stock on a central market. The overall market behavior, such as the stock price time series, is an emergent property of the agents' ...
Optoelectronic properties of (001) and (111) lattice-matched and strained quantum wire lasers--comparison with quantum well lasers
(Elsevier, 1994)
We investigate the optoelectronic properties of GaAs wires along the [001] and [111] directions for a range of cross sections and compare these with the corresponding parameters for optimized quantum wells. The relative ...
A discrete-time formulation for the variable wave speed scattering problem in two dimensions
(IOP Publishing Ltd, 1996-12-01)
Motivated by electromagnetic wave propagation in media where permittivity varies in two dimensions, we address the problem of wave scattering for two-dimensional (2D) media having variable speed. Wave speed variations are ...
Linear time detection of inherent parallelism in sequential programs
(Elsevier, 1985-07)
The topological sort can be used for the rapid detection of parallelism in sequential programs. Using this algorithm, one can detect both intrablock and interblock parallelism. The algorithm requires only information ...
Discrete Gel'fand-Levitan and Marchenko matrix equations and layer stripping algorithms for the discrete two-dimensional Schrödinger equation inverse scattering problem with a nonlocal potential
(IOP Publishing Ltd, 1998-06-01)
We develop discrete counterparts to the Gel'fand-Levitan and Marchenko integral equations for the two-dimensional (2D) discrete inverse scattering problem in polar coordinates with a nonlocal potential. We also develop ...
A generic micromachined silicon platform for high-performance RF passive components
(IOP Publishing Ltd, 2000-09-01)
This paper describes the development of a micromachined silicon platform fabricated using the dissolved wafer process that supports: (1) high self-resonance frequency and quality factor inductors suspended on a dielectric ...
