Abstract
A new transport formulation for large signal time-dependent hot electron transport in graded and abrupt heterostructures has been developed and implemented in a self-consistent ensemble Monte Carlo code. It has been used to explore the microscopic physics of Gunn diodes with a heterojunction launcher cathode. It is shown that previous frequency limits for Gunn diodes are too conservative and that a significant reduction of the dead zone at the cathode is possible with heterojunction designs.
