Charge Transfer Modeling for Charge-Coupled Devices

Abstract

ABSTRACTThe three-dimensional Poisson's equation is solved by iterative methods and the resulting electric field is used in Newton's equation to simulate electron transfer in a charge-coupled device (CCD). The time dependence of charge transfer is studied through a random walk simulation of Newton's equation. Potential obstacles of the order of 0.03 V are seen to slow charge transfer. Electron motion is also followed in two spatial dimensions through Newton's equation in order to probe a more varied set of potential obstacles.
