Transconductance as a Probe of Valley Thermodynamics in Multilayer WSe$_2$
Transconductance in multilayer WSe2 exhibits a valley-crossover signature quantified by valley susceptibility χ_v reaching ~0.20 V^{-1} in bilayer devices, absent in single-valley systems and bounded by the thermodynamic limit (4k_BT)^{-1}.
