Abstract

fetched live from OpenAlex

The tetrahedral carbon ( ta-C ) and boron doped amorphous carbon ( a-C:B ) thin films have been grown by pulsed laser deposition. The respective effects of diamond percentages by weight in the target (Dwt%) and boron percentages by weight in the camphoric carbon target (Bwt%), on the tetrahedral (sp 3 ) and trihedral (sp 2 ) bonding properties are discussed. The optical gap E g and electrical resistivity ρ increase with Dwt%, up to 1.6 eV and 5.63 × 10 7 Ω cm respectively, for the film deposited using target with 50 Dwt%. We found that the Dwt% has modified the sp 3 bonds content and the morphology of the carbon films. On the other hand, the E g of a-C:B films is almost unchanged at about 0.95 eV up to 10 Bwt% and decreases thereafter to 0.6 eV at 16 Bwt%. The ρ increases initially to 2.29 × 10 6 Ω cm at 2 Bwt%, and decreases thereafter up to 4.58 × 10 5 and 1.82 × 10 4 Ω cm at 10 and 16 Bwt%, respectively. The variation of structural properties, E g and ρ, can be related to the successful doping of B in the a-C films at low content of Bwt% (up to 10 Bwt%), as the structural properties and E g remain almost unchanged and the ρ decreased. Since both E g and ρ decreased sharply with higher Bwt%, this phenomenon can be related to graphitization. In this paper, the dependence of sp 3 and sp 2 impurity content on the growth and growth conditions of the films are also studied.

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.
