To investigate lower imprint technology without compromising performance in energy storage or communication devices, we propose to study the relatively confidential family of oxocarbic acids with remarkable (anti)ferroelectric properties: large ferroelectricity and fast transition. Nevertheless, their use in nanotechnologies is hampered by the lack of understanding of the (anti)ferroelectric switching mechanism and the difficulties in integrating them in nanodevices. To circumvent these difficulties, we offer to investigate interfacial effects in oxocarbic – graphene systems. Thanks to its very high sensibility to its dielectric environment, graphene is the perfect platform to transduce the (anti)ferroelectric state of the oxocarbic layer into a change of conductance for an easier integration into today’s technology [2]. The change of electrical polarization in a croconic acid layer (ferroelectric) or in a squaric acid layer (antiferroelectric) is expected to tune the conduction path of graphene as a function of crystallographic and orientational degrees of freedom. This master 2 project aims thus at investigating this electric proximity effect in between two class of materials of high future perspectives (molecules and graphene). The aim is to unravel the dielectric anisotropies in the (anti)ferroelectric layer and the specificities of the ferroelectric switching transition.
