A 1D coupled Schrödinger drift–diffusion model including collisions
نویسندگان
چکیده
We consider a one–dimensional coupled stationary Schrödinger drift–diffusion model for quantum semiconductor device simulations. The device domain is decomposed into a part with large quantum effects (quantum zone) and a part where quantum effects are negligible (classical zone). We give boundary conditions at the classic– quantum interface which are current preserving. Collisions within the quantum zone are introduced via a Pauli master equation. To illustrate the validity we apply the model to three resonant tunneling diodes.

Semiconductor Simulations Using a Coupled Quantum Drift-diffusion Schrödinger-poisson Model
A coupled quantum drift-diffusion Schrödinger-Poisson model for stationary resonant tunneling simulations in one space dimension is proposed. In the ballistic quantum zone with the resonant quantum barriers, the Schrödinger equation is solved. Near the contacts, where collisional effects are assumed to be important, the quantum drift-diffusion model is employed. The quantum drift-diffusion mode...
متن کاملAnalysis of a Drift-Diffusion-Schrödinger-Poisson model
A Drift-Diffusion-Schrödinger-Poisson system is presented, which models the transport of a quasi bidimensional electron gas confined in a nanostructure. We prove the existence of a unique solution to this nonlinear system. The proof makes use of some a priori estimates due to the physical structure of the problem, and also involves the resolution of a quasistatic Schrödinger-Poisson system.
متن کاملOn Collisions of Brownian Particles
We examine the behavior of n Brownian particles diffusing on the real line, with bounded, measurable drift and bounded, piecewise continuous diffusion coëfficients that depend on the current configuration of particles. Sufficient conditions are established for the absence of triple collisions, as well as for the presence of (infinitely-many) triple collisions among the particles. As an applicat...
متن کاملA Coupled Model for Radiative Transfer: Doppler Effects, Equilibrium, and Nonequilibrium Diffusion Asymptotics
This paper is devoted to the asymptotic analysis of a coupled model arising in radiative transfer. The model consists of a kinetic equation satisfied by the specific intensity of radiation coupled to a diffusion equation satisfied by the material temperature. The interaction terms take into account both scattering and absorption/emission phenomena, as well as Doppler corrections. Two asymptotic...
متن کاملSliding of Proteins Non-specifically Bound to DNA: Brownian Dynamics Studies with Coarse-Grained Protein and DNA Models
DNA binding proteins efficiently search for their cognitive sites on long genomic DNA by combining 3D diffusion and 1D diffusion (sliding) along the DNA. Recent experimental results and theoretical analyses revealed that the proteins show a rotation-coupled sliding along DNA helical pitch. Here, we performed Brownian dynamics simulations using newly developed coarse-grained protein and DNA mode...
