Extended Data Fig. 8: The ‘sunflower’ model beyond angular fit.

From: Angle-resolved transport non-reciprocity and spontaneous symmetry breaking in twisted trilayer graphene

Extended Data Fig. 8

(a) The angular dependence of longitudinal and transverse resistance, R∥ and R⊥, measured at ν = 2. (b) Measurements from different ‘sunflower’ configurations compared to the expected value extracted from a single conductivity matrix13,18. The RRMSE of the fit is 1.74%. (c) The angular dependence of longitudinal and transverse second-harmonic nonlinear transport response, 𝑉2𝜔∥ and 𝑉2𝜔⊥, measured with an AC current of 100 nA at ν = 2.
