Ionisation demonstration

The animation on this page illustrates the process of impact ionisation. The path length of the elctrons and holes is calculated using an RPL model. The animation stops when the number of carriers active in the device exceeds 100. The default values of alpha and beta should give a multiplication of 5 but due to the stochastic nature of the simulation the gain will vary between repeated runs of the simulation.

Sorry, the ionisation animation will not work in your browser. The animation requires javascript and a browser capable of displaying SVG or VML. Please try using Internet Explorer 8+, Firefox 3.6+, Seamonkey 2+, Opera 9+, Chrome 10+, Safari 5+.
