The invention discloses a solid terahertz radiator based on an edge tone effect. The solid terahertz radiator comprises an insulated substrate layer, a semiconductor conductive layer disposed on the surface of the insulated substrate layer, an insulated protective layer disposed on the surface of the semiconductor conductive layer, insulated notch grooves penetrating the semiconductor conductive layer, an input electrode, and an output electrode. The insulated notch grooves comprise a first insulated notch groove, a second insulated notch groove, and a third insulated notch groove. The first insulated notch groove and the second insulated notch groove are arranged oppositely. A gap between the first insulated notch groove and the second insulated notch groove forms a low conductive channel. One end of the third insulated notch groove is provided with a tip edge structure. The tip edge rightly faces the opening of one end, far from the input electrode, of the low conductive channel. The other end of the third insulated notch groove extends to the edge of one end of the semiconductor conductive layer. One end of the first insulated notch groove and one end of the second insulated notch groove extend to the surfaces of both sides of the semiconductor conductive layer. The solid terahertz radiator is simple in structure, easy to integrate, and capable of operating in a terahertz frequency range at normal temperature.
Description
technical field [0001] The invention relates to a solid-state terahertz radiator based on the edge-tone effect, in particular to a solid-state terahertz radiator that utilizes the edge-tone effect to cause instability to excite high-frequency radiation, and can work in the terahertz frequency band at room temperature radiator. Background technique [0002] Terahertz (1THz=10 12 Hz) radiation, usually refers to electromagnetic waves with a frequency from 100GHz to 10THz, and its corresponding wavelength ranges from 3mm to 30μm, which is between microwave and infrared waves. Recently, due to the advancement of nanotechnology, terahertz research has been applied in more fields , terahertz technology is widely used in communication technology, biological spectroscopy, remote detection of dangerous goods, food quality control, and manipulation of quantum states in semiconductors due to its non-destructive detection properties. To excite such terahertz waves requires correspondi...
