From: Gate-tunable charge carrier electrocaloric effect in trilayer graphene
The isothermal entropy changes \(-\Delta S_{e,T}\) as a function of temperature T for different gate potentials as indicated. (a) ABA-stacked trilayer graphene considering the NL-TB model, (b) ABA-stacked trilayer graphene with NNL-TB model. The chemical potential is set to \(\mu =0\) eV. Horizontal dashed line indicates \(-\Delta S_{e,T}=0\), while vertical dashed lines stand for \(T=20\) K and \(T=150\) K, where we calculate the entropies as a function of \(\mu \) in Fig. 8. Insets show a zoom for each ABA-EC response at relatively low temperatures. Note distinct vertical axes indicating different EC units.
