Klein Tunneling through Triple Barrier in AB Bilayer Graphene
Bibliographic record
Abstract
Abstract The transport properties of charge carriers in AB bilayer graphene through a triple electrostatic barrier are investigated. The transmission and reflection using the boundary conditions together with the transfer matrix method are calculated. For energy less than the interlayer coupling γ 1 , it is shown that, at normal incidence, transmission is completely suppressed in the gap for a large barrier width while it appears in the gap for the opposite case. For energy greater than γ 1 , it is shown that in the absence of an interlayer potential difference, transmission is less than that of a single barrier, but in its presence, transmission in the gap region is suppressed, as opposed to a double barrier. It is found that one, two, or three gaps can be created depending on the number of interlayer potential differences applied. Resonance in the transmission channel is observed that is not seen in the single and double barrier cases. Finally, the conductance is computed and it is shown that the number of peaks is greater than the double and single barrier cases. The results here enable the development of graphene‐based transistors.

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.
