  • Manipulating the electric state of large band gap dielectrics without any damage is quite challenging. Here, the authors demonstrate by mechanically introducing strain gradients that large electric fields are generated via flexoelectric interactions, resulting in a reversible Zener breakdown in SrTiO3, changing the resistivity by 108.

  • The development of electrically conductive fibres is attractive for wearable electronics, but performance should be maintained upon deformation and tensile strain. Here the authors fabricate flexible, stretchable, carbon nanotube-coated spandex fibres for supercapacitors and artificial muscles.

  • Charge carrier modulation in graphene by proximate ferroelectricity has attracted much attention, but it was rarely successful especially for oxide ferroelectrics mainly due to uncontrolled interfacial charge traps. In this work, the device operation of field–effect transistor comprising of graphene and ferroelectric single-crystal Pb(Mg1/3Nb2/3)O3–PbTiO3 was carefully analyzed for studying the direct or indirect coupling phenomena between charge carriers in graphene and nearby ferroelectricity.
