Long-Term Stability and Electrical Performance of Organic Monolayers on Hydrogen-Terminated Silicon
Bibliographic record
Abstract
The long-term stability (gradual oxidation) of two structurally different organic monolayers, C 6 H 5 (CH 2 ) 3 −Si≡ ( C3Ph −Si≡) and CH 3 (CH 2 ) 11 −Si≡ ( C12 −Si≡), covalently bonded to n-type silicon(111) was studied and correlated to the electrical performance of the thus formed mercury | monolayer | n-Si junctions. High-resolution XPS analysis of the O 1s region on freshly prepared samples identified physically adsorbed oxygen (O ad ) and oxygen-containing species (SiO x ) bound to silicon at 532.2 and 533.5 eV, respectively. When left under ambient conditions, both bands increased in intensity as time progressed, while no change in the carbon content (C 1s peak) was observed. More importantly, upon aging, there was a noticeable increase in the electrical current flow of both <Hg| C12 −Si≡> and <Hg| C3Ph −Si≡> junctions; a considerably larger increase occurred in the former sample, which has less oxygen content than that of the latter junction (based on the O 1s(O−Si)/Si 2p peak area ratios). These results suggest that the slow oxidation of molecularly modified silicon may, in fact, dictate the electrical performance of the thus formed molecular diode junctions.

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.
