Coherent control of electrical currents in semiconductor nanowires/‐tubes
Bibliographic record
Abstract
Abstract Quantum interference control of electrical currents is well established in bulk semiconductors. It arises from the interference of one‐ and two‐photon absorption pathways. Here, the concept is transferred to one‐dimensional semiconductor nanostructures. First, currents are optically injected into aligned single‐walled carbon nanotube ensembles by phase‐related 700 and 1400 nm, 150 fs pulses. These transient currents are detected via the emitted THz radiation. In a second set of experiments, a phase‐stable superposition of ∼100 fs pulses from a compact erbium‐doped fiber source and their second harmonic is shown to induce ultrashort ∼µA current bursts in single unbiased GaAs nanowires. The current flow is characterized by charge accumulation and the related potential difference between the contacted ends of the ∼10 µm long wires. (© 2011 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

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; both teacher heads agree on what is shown here.
