Formation of Ga<sub>2</sub>O<sub>3</sub> and NiO Thin Films at Low Process Temperatures for PN Heterojunction Diodes
Bibliographic record
Abstract
A heterojunction consisting of n-type Ga 2 O 3 and p-type NiO thin films is fabricated at low process temperatures. This technology offers the potential to improve heterojunction applications with wide bandgap semiconductors on various substrates. Optical bandgap values of 4.67 and 3.62 eV are obtained for the Ga 2 O 3 and NiO semiconductors, respectively, from a Tauc plot. The spontaneously formed depletion region in the heterojunction has capacitive characteristics under thermal equilibrium conditions, while the resistive component is involved in the charge transport under the turn-on voltage ranges. The maximum electric field at the heterojunction interface with 50 nm thick n-Ga 2 O 3 is five times higher than that of the n-Ga 2 O 3 with a thickness of over 400 nm under thermal equilibrium conditions. When the junction thickness becomes shorter than the junction depletion width, the diode suffers from an early breakdown due to the much higher maximum electric field at the PN junction interface.

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.
