Transport II This image shows a simulation of the flow of 100,000 electrons across a two-dimensional plane of electron gas. The simulated electrons are launched individually from the center, and the dark lines represent their paths. The channeling and branching structure that this image reveals is a surprising result that has implications for the design of small electronics. The image was inspired by the experiments of Mark Topinka, Brian Leroy and Professor Robert Westervelt at Harvard, and was created with the help of Scot Shaw. Eric J. Heller 2000 Courtesy of Eric J.
