Related matrix context

This claim does not itself create a matrix cell. The context below belongs to Phonon drag, the phenomenon it is about.

D = disequilibrium row · C = coupling family column. A cell reads the state of the atlas for that pair.

Notes

Phonon drag is a component of the same conductor's Seebeck coefficient, not a second converter in series with it: Yalamarthy et al. 2019 attribute up to 32 % (300 K) and 88 % (50 K) of the Seebeck coefficient of a thick AlGaN/GaN 2DEG to drag. The compiler therefore treats the heat-conduction → phonon-drag spelling as representation-equivalent to the thermoelectric generator.
