Abstract
Two-dimensional computer simulations of charge collection phenomena in GaAs MESFETs have been performed for alpha and laser ionization. In b oth cases more charge is collected than is created by the ionizing eve nt. The simulations indicate that a bipolar transport mechanism (t < 6 0 ps) and a channel modulation mechanism (t > 40 ps) are responsible f or this enhanced charge collection.
