Proton-Induced Transient Charge Collection in GaAs and InAlSb/InAs-Based FETs
Bibliographic record
Abstract
The single-event transient (SET) response of two different n-channel III-V field-effect transistor technologies (GaAs MESFET, InAlSb/InAs HEMT) is measured for the first time for MeV proton irradiation. The characteristics and mechanisms of the proton-induced response of these two technologies are presented and discussed in terms of previous heavy-ion and pulsed-laser measurements. The measurements show that the maximum collected charge, event cross section, pulse amplitude, and full width at half-maximum (FWHM) all increase with increasing proton energy, and decrease as the devices are biased more strongly in depletion. The results are consistent with the presence of charge-enhancement processes that are a consequence of ionization-induced hole accumulation in the substrate/buffer regions of the devices. The InAlSb/InAs HEMT measurements reveal at least an order-of-magnitude lower sensitivity to proton-induced transient generation than the GaAs MESFET in terms of both collected charge and cross section.

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.
