抜粋

We report experimental observation of electron (e-)/hole (h +) layer on the clean surface of insulating pure BaTiO3 single crystals in ultra high vacuum (UHV <10-8 Pa). To our knowledge this is the first report of the bipolar surface carrier layer by the field effect on any oxide. The experiments here verify that both accumulation and inversion occur and the surface carrier layer is intrinsic, i.e., due to spontaneous polarization PS not to impurities and defects.
