Exact branch-transfer criterion for common-mode Thomson heat cancellation in thermoelectric couples
Peng Kang, Da Wan, Shulin Bai +7
Thermoelectric p- and n-type legs are commonly paired by matching their Seebeck magnitudes, although a cooler responds to heat transported through its complete electrical and therm…

Broadband phonon-velocity suppression and a finite anisotropic crossover in twisted bilayer SnSe
Peng Kang, Wei Yin, Da Wan +9
Moiré superlattices reshape lattice dynamics without altering chemical composition, yet how crystal anisotropy modifies this control remains unclear. We combine density-functional-…
