High Gain ZnO Nanowire Phototransistor

Not Accessible

Your library or personal account may give you access

Abstract

We demonstrate the potential of nanowires as phototransistors with internal gain. Two- terminal single ZnO nanowire devices have been fabricated, which under UV illumination, show high photoconductive gain (approaching 1010) due to hole-trapping at surface states.
