Abstract

fetched live from OpenAlex

The influence of self-assembled trimesic acid (TMA) on the electronic properties of a heavily boron-doped silicon surface was investigated using first-principles DFT calculations. Our results demonstrate that the adsorption of isolated TMA molecules, small molecular islands, or complete monolayers is characterized by significant adsorption energy and electron charge transfer to the Si–B interface, while the bonding character of TMA to the surface remains essentially noncovalent. The stability of the adsorbed species was ensured by an attractive interaction from the Si–B interface but also through the formation of hydrogen bonds between TMA units. Beyond this significant stability of the different TMA adlayers, the weak dispersion and the energy level position of states associated with the TMA moieties observed in the band gap region of the Si–B interface suggest that the adsorbed layer can be used to tune the electronic properties of the substrate.

Teacher imitation

Not 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.
