Low-force pulse switching of ferroelectric polarization enabled by imprint field
Switching barrier lowering by imprint field
We first explain the strategy for enabling low-force polarization switching by introducing an imprint field via asymmetric electrostatic boundary conditions in ferroelectric materials. As known, the…
