2D MoSe<sub>2</sub> Geometrically Asymmetric Schottky Photodiodes
Bibliographic record
Abstract
Abstract Optoelectronic devices based on geometrically asymmetric architecture have recently attracted attention due to their high performance as photodetectors and simple fabrication process. Herein, a p‐type 2D MoSe 2 photodetector based on geometrically asymmetric contacts is reported for the first time. The device exhibits a high current rectification ratio of ≈10 4 and a large self‐powered photovoltage responsivity of ≈4.38 × 10 7 V W −1 , as well as a maximum photocurrent responsivity of ≈430 mA W −1 along with a response time of ≈2.3 ms under 470 nm wavelength at 3 V bias voltage. The photocurrent responsivity is further enhanced to an ultrahigh responsivity of ≈1615 mA W −1 by applying a gate bias voltage due to the electrostatic modulation of carrier concentration in the MoSe 2 channel. The simple fabrication process of the geometrically asymmetric MoSe 2 diodes along with their high photodetection and diode rectifying performance make them excellent candidates for electronic and optoelectronic applications.

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.
