N2 - In the present study, high-sensitivity photodetection has been demonstrated using an amorphous selenium (a-Se) based photodetector driven by nitrogen-doped diamond cold cathode. The emission current-applied voltage characteristics are compared between different lighting conditions, and their sensitivities are evaluated in terms of nominal quantum efficiency. The estimated nominal quantum efficiency was 10-40 for visible and up to 1000 for ultraviolet, proving a successful photodetection utilizing carrier multiplication in a-Se.
