Minority carrier diffusion lengths and mobilities in low-doped n-InGaAs\n for focal plane array applications
Bibliographic record
Abstract
The hole diffusion length in n-InGaAs is extracted for two samples of\ndifferent doping concentrations using a set of long and thin diffused junction\ndiodes separated by various distances on the order of the diffusion length. The\nmethodology is described, including the ensuing analysis which yields diffusion\nlengths between 70 - 85 um at room temperature for doping concentrations in the\nrange of 5 - 9 x 10^15 cm-3. The analysis also provides insight into the\nminority carrier mobility which is a parameter not commonly reported in the\nliterature. Hole mobilities on the order of 500 - 750 cm2/Vs are reported for\nthe aforementioned doping range, which are comparable albeit longer than the\nmajority hole mobility for the same doping magnitude in p-InGaAs. A radiative\nrecombination coefficient of (0.5-0.2)x10^-10 cm^-3s^-1 is also extracted from\nthe ensuing analysis for an InGaAs thickness of 2.7 um. Preliminary evidence is\nalso given for both heavy and light hole diffusion. The dark current of\nInP/InGaAs p-i-n photodetectors with 25 and 15 um pitches are then calibrated\nto device simulations and correlated to the extracted diffusion lengths and\ndoping concentrations. An effective Shockley-Read-Hall lifetime of between\n90-200 us provides the best fit to the dark current of these structures.\n

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.
