Depletion-Mode A-GaO<sub><i>x</i></sub> Solar-Blind Phototransistors for Optoelectronic Mixed Logic Gate Circuit and Solar-Blind Imaging
Bibliographic record
Abstract
Phototransistors based on Ga 2 O 3 are widely used in civil or military applications as a three-terminal device with solar-blind characteristics. This study constructed amorphous gallium oxide (a-GaO x ) thin film transistor (TFT)-based solar-blind photodetectors and explored the effect of the oxygen partial pressure on films and devices. It had been found that there is a strong correlation between oxygen partial pressure and photodetector properties. Decreasing oxygen partial pressure increases the carrier concentration, resulting in a shift of device threshold voltage ( V th ) from 15 V to −5 V, thereby causing the device to transition from enhancement mode to depletion mode. And the a-GaO x TFT-based solar-blind photodetector in depletion mode has an ultrahigh performance, with a responsivity ( R ) of 1038 A/W and an I on / I off ratio of 10 7 at a gate voltage (V G ) of −5 V and a responsivity of 2100 A/W at a V G of 100 V. And the reconfigurable basic logic functions (“AND”/“OR”) have been achieved. Furthermore, the imaging is realized by assembling a-GaO x thin film transistor-based solar-blind photodetector arrays (a-GaO x TFT-PDAs).

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
