Dicarbon defects in as-grown and annealed carbon-doped InAs
Bibliographic record
Abstract
Annealing measurements performed on heavily carbon-doped InAs samples grown by organometallic vapor phase epitaxy confirm that the n-type behavior observed in this material is due to the formation of dicarbon donor defects. The structural, electrical, and optical properties of n-type carbon-doped InAs annealed at temperatures of 400 °C and higher were studied. Raman and infrared spectroscopy showed a reduction in the intensity of carbon acceptor and carbon-hydrogen lines along with an increase in the strength of the dicarbon local vibrational mode after annealing. X-ray diffraction revealed that the lattice constant of annealed samples increased toward that of the undoped samples. These changes were accompanied by increases in the electron concentration and mobility. Based on the expected energy level of dicarbon donors in GaAs, we predict that the dicarbon defects in InAs should introduce a resonant level close to or slightly above the conduction band minimum.

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.
