DOI: 10.1063/5.0269417
Abstract: Ferroelectric ceramics typically exhibit ultrahigh flexoelectric coefficients that far exceed theoretical values due to various extrinsic factors. It has been demonstrated that the high values are mostly contributed by the surface piezoelectric response of spontaneously… read more here.

DOI: 10.1103/physrevb.97.195405
Abstract: In spin-polarized surface positronium annihilation measurements, the spin polarizations of graphene and h-BN on Co(0001) were higher than those on Ni(111), while no significant differences were seen between graphene and h-BN on the same metal.… read more here.
