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…

Hybrid antiferroelectric-ferroelectric domain walls in noncollinear antipolar oxides
Ivan N. Ushakov, Mats Topstad, Muhammad Z. Khalid +15
Antiferroelectrics are emerging as advanced functional materials and are fertile ground for unusual electric effects. For example, they enhance the recoverable energy density in en…

AFM-based Functional Tomography-To Mill or not to Mill, that is the Question!
Niyorjyoti Sharma, Kristina M. Holsgrove, James Dalzell +8
The electrical response of ferroelectric domain walls is often influenced by their geometry underneath the sample surface. Tomographic imaging in these material systems has therefo…
