Problems solved by technology

In actual operation, the beam of this diode needs to be clamped by tools, so it is easy to bend and break during the assembly process. Once there is a problem with one end of the beam, the device cannot be installed on the circuit normally, and the device will be invalidated. Due to the current high-performance frequency doubling Schottky diodes are relatively expensive, which increases the cost of scientific research to a certain extent

Description

technical field [0001] The invention relates to the technical field of semiconductor devices. Background technique [0002] Terahertz (THz) waves refer to electromagnetic waves with a frequency in the range of 0.3-3THz. The generalized terahertz wave frequency refers to 100GHz to 10THz, where 1THz=1000GHz. THz waves occupy a very special position in the electromagnetic spectrum, and THz technology is recognized as a very important cross-frontier field by the international scientific and technological community. [0003] In the low-end range of THz frequency, the solid-state source is usually obtained by frequency doubling of semiconductor devices. This method doubles the frequency of the millimeter wave to the THz frequency band through a nonlinear semiconductor device, and has the advantages of compact structure, easy adjustment, long life, controllable waveform, and normal temperature operation. At present, short-wavelength submillimeter wave and THz solid-state sources ...
