Abstract

The invention provides a photoelectric detector. The photoelectric detector comprises a photoelectric detection layer and a first electrode layer, wherein the first electrode layer is arranged on a surface of one side of a photoelectric layer to obtain a photoelectric detection structure, and the photoelectric detection layer is formed by fabrication of a two-dimensional material or a two-dimensional material heterojunction structure. Since the two-dimensional material or the two-dimensional material heterojunction structure is sensitive to light and is simultaneously thin (the thickness is smaller than 1 nanometer), the probability of reaction with radiation particles is extremely small, and the false triggering probability is extremely small; and moreover, an acting force among atoms ina two-dimensional material plane is relatively high, the photoelectric detector is stable in structure, and the damage generated by the radiation particle is relatively small.

Description

Technical field [0001] The present invention relates to the field of semiconductor technology, in particular to a photodetector. Background technique [0002] With the development of aerospace technology, various new types of artificial satellites and spacecraft have been put into space. In order to achieve more functions, artificial satellites and spacecraft carry a large number of electronic and optoelectronic devices. However, spacecraft in space will be exposed to various radiations, which can cause serious damage to integrated electronic chips, affect the performance of devices, and even damage these integrated electronic chips, causing irreparable losses. [0003] In addition, in the nuclear industry, a large number of intelligent chips are also needed. Especially in the rescue of nuclear accidents, precision electronic and optoelectronic devices such as robots are required. Nuclear weapon explosions will also pose a serious threat to various electronic and optoelectronic co...
