Abstract
Silicon PIN neutron detectors play an important role in nuclear science with advantages such as small size, light weight, low cost, and mature manufacturing process. This paper proposes a self-powered neutron detection system based on a triboelectric nanogenerator (TENG) and silicon PIN diode for the first time. The proposed environmentally efficient and low-cost TENG is connected to the detector through a rectifier bridge circuit. When the TENG powered silicon neutron detector is irradiated, the PIN diode generates defects in the silicon body, which leads to a decrease in the lifetime of excess carriers. The neutron dose can be measured by monitoring the change of the terminal voltage of the PIN diode.
