Claim 12:
13. A method for generating terahertz radiation, comprising:
providing 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), and
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 laser irradiation;

applying (S110) a supply voltage to the Gunn diode; and
irradiating (S120) the Gunn diode with a laser beam in order to trigger or support a charge carrier transfer in the active layer (130) of the Gunn diode.
