Enhanced flexoelectricity at reduced dimensions revealed by mechanically tunable quantum tunnelling

Flexoelectricity exists in every dielectric material exposed to a strain gradient and is enhanced at the nanoscale. However, precisely determining flexoelectric coupling parameters at the nanoscale is challenging, but has been overcome here by measuring the current across a tunnel junction.
