Abstract

fetched live from OpenAlex

We have analyzed the device properties of a single-wall metallic carbon nanotube operated as a parametric electron pump. It is found that a dc current can be pumped out from this molecular device by a cyclic variation of two gate voltages near the nanotube, in the absence of any bias voltage. Due to the particular electronic properties of the nanotube, the pumped current is found to show a remarkable parity effect near the resonant levels, with a rather sensitive dependence on the control parameters of the device such as deformation strength, the amplitude and the phase difference of the gate voltage.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
