Claim 0:
1. A Gunn diode, comprising:
a first contact layer (110) and a second contact layer (120);
an active layer (130) based on a gallium nitride (GaN) semiconductor material which is formed between the first contact layer (110) and the second contact layer (120);
a substrate (140) on which the active layer (130) is formed with the first contact layer (110) and the second contact layer (120);
an optical input (150) for a laser (50) in order to facilitate or trigger a charge carrier transfer between extrema (210, 220) of the energy bands of the active layer (130) by means of laser irradiation; and
a field plate (170), made of metal, wherein the active layer (130) is formed between the field plate (170) and the substrate (140), without protruding laterally over the field plate (170).
