Electron flow. Computer model representing the flow of electrons through a two-dimensional electron gas (2DEG). The 'gas' is composed of many free electrons,which can move around in only one plane. The 2DEG possesses an electric potential. Irregularities in this potential produce a 'bumpy' surface. The model shows the paths taken by electrons released one at a time into the gas. The negatively-charged electrons were deflected by the bumps in the gas,producing a branching pattern,with the greatest density of electrons represented by the darkest areas. The electron flow was modelled by Professor Eric Heller,Harvard University,Cambridge,Massachusetts,USA | |
