Abstract
Disclosed herein are nanoscale devices comprising one or more ferroelectric nanoshells characterized as having an extreme curvature in at least one spatial dimension. Also disclosed are ferroelectric field effect transistors and metal ferroelectric metal capacitors comprising one or more ferroelectric nanoshells. Methods for controlling spontaneous ferroelectric polarization in nanoshell devices are also disclosed.
