Scanning Tunneling Microscopy and Spectroscopy Studies of Individual Lander Molecules Anchored on a Copper Oxide Nanotemplate
Bibliographic record
Abstract
By means of scanning tunneling microscopy (STM), scanning tunneling spectroscopy (STS), and current image tunneling spectroscopy (CITS), we have studied the electronic properties of individual “Lander” molecules anchored on a nanopatterned Cu(110) surface. To hinder surface diffusion during STM and STS imaging and spectroscopy studies at room temperature, the molecules are immobilized in the troughs of the Cu−O nanotemplate which forms on the Cu(110) surface by exposure to oxygen at high temperature. STS spectra extracted from CITS images reveal no lateral dependency over the molecules, which indicates that the electronic features above the center of the molecules as well as above the four spacer legs are very similar. An electronic gap of ∼2.2 eV was determined from the d I /d V spectra, which is tentatively ascribed to the highest occupied molecular orbital (HOMO)−lowest unoccupied molecular orbital (LUMO) gap of the Lander molecules.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
