Opto-electrical evaluation of visible blind fast-response nanostructured SnO₂/Si photodetector.

ABSTRACT: In this study, a nanostructured tin(iv) oxide (SnO₂)/Si heterojunction UV photodetector was fabricated in response to laser pulses attained via pulsed laser deposition (PLD). In particular, the photo-detection mechanisms of the proposed devices were thoroughly investigated considering multiple-profile dependency, namely, laser pulses, spectral response, and incident power. In detail, particle diameters of 25 and 41 nm with a bandgap alteration of 0.2 eV and a cut-off phenomenon at around 335 nm occurred as a result of an increase in the number of pulses from 300 to 700. The optimum photodetector (at 700 pulses, λ ₃₄₀ nm, and 10 mW cm^-2) revealed a responsivity (R _λ ) and external quantum efficiency (EQE) of 32.9 mA W
