Fig. 5: Interband LPGE susceptibility σabc of bilayer and trilayer WTe2 at μ = 0.

From: Ferroelectric nonlinear anomalous Hall effect in few-layer WTe2

Fig. 5

a σabc for the ±mFE states of bilayer WTe2. b σabc for the ±iFE state of trilayer WTe2. These two plots demonstrate that, under ferroelectric transition, the sign of LPGE-induced dc current susceptibility switches in the trilayer case, but remains invariant in the bilayer case.
