摘要：

A novel field emission type infrared light sensor was proposed and demonstrated. The electron emission phenomena from pyroelectric material by infrared light irradiation were confirmed. The electron emission current increased rapidly and decayed slowly when a step infrared light was irradiated, and the peak emission currents were proportional to the incident infrared light power. The emission efficiency was 35%. We constructed a prototype image sensor by using the electron emission device as a photocathode, and infrared light image was successively taken.
