Thermoelectric Optimization through Quantum–Classical Transport Crossover in WSe₂ Nanojunctions

Significance  Figure 4. Contour plots depict the quantum-to-classical transition. Contour plots of ζ ≡ (GSC–GQM)/(GSC+GQM) are shown as functions of temperature (250–500 K) and gate voltage Vg (−1.5 to 1.5 V) for Pt–WSe2–Pt thermoelectric junctions with channel lengths Lch= (A) 3 nm, (B) 6 nm, (C) 9 nm, and (D) 12 nm. ζ(T, Vg) represents competitive strength between quantum mechanical (shown in blue) and …
