Abstract

Abstract

In this paper, radiation effects of 1 MeV electron on short wavelength Hg1-xCdxTe photovoltaic detectors have been studied. Response spectrum, currentvoltage characterization and detectivity were measured before and after irradiation to analyze the radiation effects. It's been observed that after irradiation, the response spectra of detectors become narrower at shot wavelength while the peak and cutoff wavelength have no noticeable change. The dark current of devices increases with the irradiation dosage increasing and the detectivity thus decreases.
