Suppressing premature edge breakdown for InP/InGaAs avalanche photodiodes by modeling analyses
Bibliographic record
Abstract
In this work, based on the advanced drift and diffusion model with commercial software, the Crosslight APSYS, twodimensional photoresponsivity behavior for the InP/InGaAs separate absorption, grading, charge and multiplication avalanche photodiodes have been modeled to analyze suppressing premature edge breakdown. Basic physical quantities like band diagram, photon absorption, carrier generation and electric field as well as performance characteristics such as photocurrent, multiplication gain, and breakdown voltage etc., are obtained and selectively presented. Modeling results indicate that an etched mesa structure with the charge sheet layer can effectively suppress the premature edge breakdown in the device periphery region. Optimization modeling results with mesa step height are also demonstrated. Approach to model complex guard ring structure with double diffusion is further explored. Possible combination of Crosslight CSuprem diffusion profile is also discussed.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
