A Comparative Study on the Effects of Planarity of Access Region on the Low-Frequency Noise Performance of InAlN/GaN HFETs
Bibliographic record
Abstract
The low frequency drain noise-current characteristics of metallic-face InAlN/AlN/GaN heterostructure field effect transistors (HFETs) having fin structures only under the gate, while maintaining a planar structure in the access regions, are compared to those of the HFETs having fin structures stretched from source to drain. Evidence indicates that both device types follow the trends of carrier number fluctuation (CNF) with correlated mobility fluctuation (CMF) model of 1/f noise. Accordingly, the noise of the gated channel has been identified as the dominant noise source for both device types. Devices from the former category exhibit improved 1/f noise performance with lower drain noise-current spectral density. This observation could be due to presence of a higher two-dimensional electron gas (2DEG) concentration under the gated-channel overshadowing the carrier number and mobility fluctuations.

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.
