4/2/2020· The deep-UV-to-visible rejection ratio exceeded 10 6 while the deep-UV-to-near UV rejection exceeded 10 3. The thermal-noise limited detectivity was estimated to be 4 × 10 14 cm Hz 1/2 W −1 . Hopping conduction along screw disloion-mediated localized trap states was found to be the dominant carrier transport mechanism in the samples exhibiting high reverse leakage.
