From: Gate-tunable charge carrier electrocaloric effect in trilayer graphene
Electrocaloric response for ABC-stacked trilayer graphene. (a) Isothermal entropy changes \(-\Delta S_{e,T}\) as a function of T, the chemical potential is set to \(\mu =0\). Dashed vertical lines indicate \(T=30\) K and \(T=300\) K, where we calculate the electronic entropy in (b) and (c) respectively. The inset in (a) shows \(-\Delta S_{e,T}\) for higher temperatures. Note distinct vertical axes in (a) indicating different electrocaloric units. In (b) and (c) vertical dashed lines indicate \(\mu =0\) eV where we obtain the EC effect in (a).
