Abstract
The lucky drift theory developed by B.K. Ridley (1983) is modified to include the effect of field variation over the 'dead space'. The new theory is applicable to small-geometry logic devices for which the total energy available from the supply voltage is comparable to the ionisation threshold energy. It is shown that the new theory predicts a substantially lower level of multiplication than do conventional theories based on an ionisation coefficient.Keywords
