The InP/GaAsSb type-H heterostructure system and its application to high-speed DHBTs and photodetectors: physics, surprises, and opportunities (INVITED)
Bibliographic record
Abstract
The InP/GaAsSb/InP "type-II" heterostructure system is of interest for high-speed devices such as photodetectors and double heterostructure bipolar transistors (DHBTs) because its band alignment enables the straightforward injection of electrons from a ~0.72 eV p-type GaAsSb layer into n-type InP without any need for interface grading. We briefly review the salient features of the InP-GaAsSb system, and consider some of the surprising device characteristics encountered in InP/GaAsSb -based devices. In several respects, the InP/GaAsSb system is shown to offer very appealing opportunities for the development of high-speed NpN DHBTs with ultrathin base and collector layers

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.
