PtSe<sub>2</sub> Field-Effect Transistors: New Opportunities for Electronic Devices
Bibliographic record
Abstract
PtSe2, a new family of transition metal dichalcogenides, has been explored for electronic device applications using density functional theory and non-equilibrium Green's function within the third nearest neighbor tight-binding approximation. Interestingly, despite its small effective mass (me* as low as 0.21m0; m0being electron rest mass), PtSe2has large density of states due to its unique six-valley conduction band within the first Brillouin zone, unlike MoX2family. This has direct impacts on the device characteristics of PtSe2field-effect transistors, resulting in superior on-state performance (30% higher on current and transconductance) as compared with the MoSe2counterpart. Our simulation shows that the PtSe2device with a channel longer than 15 nm exhibits near-ideal subthreshold swing, and sub-100 mV/V of drain-induced barrier lowering can be achieved with an aggressively scaled gate oxide, demonstrating new opportunities for electronic devices with novel PtSe2.

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.
