Résumé. Par le formalisme de la matrice de transfert, le coefficient de transmission ainsi que la longueur de localisation sont étudiés dans le cas d’un superréseau (SR) a ̀ base de semi-conducteur en trimer hauteur de barrière (THB). Nous nous sommes intéressés au superréseau, forme ́ par un empilement de couche d’épaisseur constante du semi-conducteur GaAs/AlxGa1−xAs. La concentration x en aluminium prend au hasard, deux valeurs différentes, avec la condition que l’une d’entre elles apparâıt seulement en triplée. Les états électroniques du SR ont éte ́ étudiés par le calcul théorique du coefficient de transmission de la structure de minibande. Nous avons observe ́ que le processus de délocalisation existe quand le désordre est corrélé, résultat confirmant les espérances théoriques déja ̀ trouve ́ pour le cas du dimer. Abstract. By the formalism of transfer matrix, transmission coefficient and lo-calization length are studied in the case of a superlattice containing semiconductor in barrier height trimer (HBT). We are interested in the GaAs/AlxGa1−xAs layers, having identical thickness, where the aluminium concentration x takes at random two different values, with the constraint that one of them appears only triply, i.e. it is a random trimer barrier (RTB). The electronic states of SR were studied by theoretical calculation of transmission coefficient of the miniband structure. We observed that the process of delocalization exists when the disorder is correlated, the result confirming the theoretical studies already found for the case of the dimer.

Full frame distilled prediction

Teacher imitation

Not 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.
