Gate-tunable charge carrier electrocaloric effect in trilayer graphene [PDF]
Scientific Reports, 2021 The electrocaloric (EC) effect is the change in temperature and entropy of a material driven by the application of an electric field. Our tight-binding calculations linked to Fermi statistics, show that the EC effect can be produced in trilayer graphene (

Origins of the Inverse Electrocaloric Effect. [PDF]
Energy Technol (Weinh), 2018 AbstractThe occurrence of the inverse (or negative) electrocaloric effect, where the isothermal application of an electric field leads to an increase in entropy and the removal of the field decreases the entropy of the system under consideration, is discussed and analyzed. Inverse electrocaloric effects have been reported to occur in several cases, for
