Electron transport in double bridges system
Journal Title: JOURNAL OF ADVANCES IN PHYSICS - Year 0, Vol 9, Issue 2
Abstract
In this paper we investigate theoretically the effect of introducing wide band, and Narrow band approximations for the bridge energy band on the electron transport process (ET) through the donor-bridges-acceptor (DBA) system. We using one electron model, for which the Hamiltonian of the system consists of a single-level for both Donor and Accepter (i.e. QD) both coupled to a band bridge as a tight binding interaction. The time dependent Schrödinger equation give us a formula for the occupation probabilities for donor and acceptor levels. The probability of (ET) to the donor and accepter is small because the electron accumulated on the bridge units. Also, the current of acceptor and the effect of different system parameters are studied.

Introduction to The Spiral Dynamics and The Spiral Coriolis Force
The spiral dynamics of a point-like body of mass m in spiral differential geometry are introduced. New ideal motions have been studied, the uniform spiral motion and the uniform spiral-polar motion. The analysis is propo...
The study on the eect of Ruthenium(Ru) in LaFeAsO
We study the eect of Ru substitution at Fe site on LaFe1xRuxAsO compounds for x = 0, 0.25, 0.50, 0.75 and 1. We produce density of state (DOS), Fermi surface (FS) and a band structure based on Density Functional Theory(D...
