Design and Experiment of Graphene-based Space Radiation Detection Sensor

In order to verify the performance of the graphene-based space radiation detection sensor,the radiation detection principle based on two-dimensional graphene material was analyzed according to the band structure and electric field effect of graphene.The method of space radiation detection based on graphene is studied.And then a new type of space radiation sensor samples with small volume,high resolution,radiation-resistance are formed.Using proton and electron,the electrical performance of GFET radiation sensor is verified.The designed graphene space radiation detection sensor is expected to be applied in the radiation environment monitoring of the space station and the moon,and can also achieve technological breakthroughs in pulsar navigation and other fields.
