Ballistic electron emission microscopy studies of ZnSe–BeTe heterojunctions
Bibliographic record
Abstract
Ballistic electron and hole emission microscopies, have been used to probe Au/ZnSe/GaAs and Au/ZnSe/BeTe/GaAs (001) heterostructures as a function of the ZnSe/BeTe interface stoichiometry. Ballistic electron and hole transport into n- and p-type ZnSe epilayers, respectively, were observed with spectra that conformed well to theoretical behavior. The measured average voltage thresholds +1.25 (p type) and −1.41 V (n type) were in good agreement with previously observed values for the Au/ZnSe Schottky barrier heights and consistent with the value of the ZnSe direct band gap (2.67 eV). However, the ballistic transport into the BeTe conduction bands required to measure the ZnSe/BeTe conduction band offset was not confirmed. Time-dependent and spatial variations of the voltage thresholds were observed for p- and n-type diodes, with and without BeTe epilayers, and were presumed to be linked to switching Fermi level pinning positions from varying Au/ZnSe interface states densities.

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.
