We present an algorithm for self-consistent solution of the Poisson and Schrodinger equations in two spatial dimensions with open-boundary conditions to permit current flow. The algorithm works by discretely sampling a device's density of states using standing wave boundary conditions, decomposing the standing waves into traveling waves injected from the contacts to assign occupancies, and iterating the quantum charge with ...

The effects of pulse shape on self-phase modulation on 10-Gb/s pulse transmission over dispersion compensated fiber links using dispersion compensating fiber technique are investigated numerically. The transmission performance of a dispersion compensated fiber link using standard single-mode fiber is evaluated when the input pulse varies from a Gaussian to a super- Gaussian pulse with very sleeper leading and trailing edges. ...

We present an algorithm for self-consistent solution of the Poisson and Schrodinger equations in two spatial dimensions with open-boundary conditions to permit current flow. The algorithm works by discretely sampling a device's density of states using standing wave boundary conditions, decomposing the standing waves into traveling waves injected from the contacts to assign occupancies, and iterating the quantum charge with the potential to self- consistency using a novel hybrid Newton-Broyden method. A double-gate FET is simulated as an example, with applications focused on surface roughness and contact geometry.
The effects of pulse shape on self-phase modulation on 10-Gb/s pulse transmission over dispersion compensated fiber links using dispersion compensating fiber technique are investigated numerically. The transmission performance of a dispersion compensated fiber link using standard single-mode fiber is evaluated when the input pulse varies from a Gaussian to a super- Gaussian pulse with very sleeper leading and trailing edges. The interaction between SPM and GVD are stronger for a pulse with steeper leading and trailing edges.
In this paper, an efficient non-iterative approach for calculating the threshold voltage of the nanoscale double gate nMOSFET is presented. First, it is shown that the parabolic potential is a reasonable approximation for the body potential along the coordinate normal to the interfaces at the threshold of conduction. Then, the energies of confined carriers are determined by solving the Schrodinger's equation using the WKB approximation. All the coefficients of the potential polynomial are represented analytically in the threshold condition. To assess the accuracy of the proposed model, its predictions have been compared to the results of a numerical simulator and a previously published model. It is also observed that the approach can be extended to an iterative threshold voltage model for 4-terminal fully depleted SOI structures with intrinsic or doped body.
In this work, we quantitatively investigate the space-charge-limited current in quantum regime by solving the Schrodinger-Poisson equation based on the finite element method (FEM). The paper shows the schematic of the self- consistent model of coupled Schrodinger and Poisson's equation for a nano- diode gap, where psir(x)=A exp(ik1x) is an incident plane wave, and psir(x)=B exp(-ik1x) and psit(x)= C exp(ik2x) are a reflected plane wave and a transmitted plane wave, respectively. The boundary conditions to Eqs. (1) and (2) are formulated as follows. Let Vgbe the gap bias voltage, which may be zero, positive, or negative.
Numerically, we have analyzed the basic characteristics of all-optical demultiplexing based on four-wave mixing in semiconductor optical amplifiers by solving a modified nonlinear Schrodinger equation using the finite- difference beam propagation method. For high on-off ratio, the optimum input pump pulsewidth is 1~3 ps for 1 ps, 250 Gbit/s probe pulse. From the simulation results, it is clear that for the faster demultiplexing operation, semiconductor optical amplifiers with wider gain bandwidth are required. We have simulated pattern effects in the FWM signal. We have also obtained demultiplexing from the time-multiplexed signals by repetitive pump pulses
As MOSFET channel lengths approach the nanoscale, the reliability of semi- classical transport models decreases. To offer additional insight into transport phenomena in these deeply scaled devices, simulation tools that treat quantum transport without sacrificing the realistic treatment of scattering are needed. A unique non-equilibrium Green's function approach "Schrodinger Equation Monte Carlo" (SEMC) has been developed that provides a physically rigorous approach to quantum transport and phase-breaking inelastic scattering via real (actual) scattering processes such as optical and acoustic phonon scattering. Quasi-one-dimensional SEMC codes previously have been applied to study essential quantum transport physics in devices such as quantum well lasers where the potential varies only along the nominal direction of transport, although with a fully three-dimensional (3D) treatment of scattering. However, such 1D analysis cannot provide quantitatively accurate results for 2D MOSFET structures, and, in particular, lacks the capability of self-consistency with respect to the potential profile. In this paper, the development of a "SEMC-2D" code for electrostatically self- consistent treatment of quantum transport within devices with, additionally, quantum confinement normal to the direction of transport, is reported along with illustrative simulation results for nano-scaled SOI MOSFETs geometries.
While bulk silicon is a poor emitter of light, silicon nanocrystals are shown to be promising materials for light-emitting devices. Despite all the efforts on the fabrication and modeling of silicon nanostructures, the origin of their light emission is still controversial. In this paper we investigate models that have been proposed for silicon nanostructures. A simple model based on solving the Schrodinger equation for quantum dots for light emission in silicon nanocrystals has been proposed. It is shown that quantum confinement is responsible for luminescence in the red portion of spectrum, while the surface passivants are responsible for emission in the blue and green region of the spectrum. The validity of this modeling has been proven by experimental data.
It is shown that the dynamics of optical pulse propagation in lumped amplified systems is described by the lossless nonlinear Schrodinger equation under the condition that the amplifier spacing is short compared to the nonlinear evolution length scale. The errors involved in this description are quantified and are on the order of the square of the amplifier spacing. The authors also consider an alternative method of pulse preemphasis which has been proposed, and they show how it relates to the average soliton method presented.<<ETX>>
