Low-Field Ferroelectric Switching realised by Forced Harmonic Oscillation of Domain Walls
Niyorjyoti Sharma, Nathan Black, Joseph G. M. Guy +6
Conventionally, dc fields are used for switching dipole orientations in ferroelectrics. Such fields tilt the potential surface experienced by domain walls and thereby lower activat…
