MOS Interface Characteristics of <i>In Situ</i> Ge-Doped 4H-SiC Homoepitaxial Layers
Bibliographic record
Abstract
We report on the electrical characterization of the Metal-Oxide-Semiconductor (MOS) interfacerealized on in-situ Ge-doped n-type 4H-SiC epilayers grown by Chemical Vapour Deposition(CVD). In order to study the relevance of this novel material for MOSFET technology, and in particularwhether the Ge presence deteriorates the SiC/SiO2 interface, we investigated the electrical propertiesof MOS capacitors realized on this novel substrate. Capacitance-Voltage measurements, performedto determine the quality of the SiC/SiO2 interface, show that the interface traps concentration is notincreased by the Ge content. The current through the oxide layer, monitored to study the bulk oxidequality and the tunneling mechanisms, indicates that Fowler-Nordheim conduction occurs and that thesubstrate-to-oxide barrier for electrons is comparable to the reported values for the SiC/SiO2 system.

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.
