  • Abstract
    Current-voltage characteristics obtained by pulse-biasing GaN Gunn diodes on GaN substrate showed a wide negative differential resistance (NDR) region. Electrical fields of up to twice the threshold value did not lead to any electromigration effects from the contacts. The electron drift-velocity (vD) was estimated to be 1.9times107 cm/s. This represents the first demonstration of a stable NDR with a vertical GaN-based Gunn device
