UV and deep-UV selective photodiodes from visible-blind to solar-blind were realized based on a
Si-doped (InxGa1–x)2O3 thin film with a monotonic lateral variation of 0.0035<x<0.83. Such
layer was deposited by employing a continuous composition spread approach relying on the ablation
of a single segmented target in pulsed-laser deposition. The photo response signal is provided
from a metal-semiconductor-metal structure upon backside illumination. The absorption onset was
tuned from 4.83 to 3.22 eV for increasing x. Higher responsivities were observed for photodiodes
fabricated from indium-rich part of the sample, for which an internal gain mechanism could be
identified. VC 2016 AIP Publishing LLC.
