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…
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…
Spatially Resolved High Voltage Kelvin Probe Force Microcopy: A Novel Avenue for Examining Electrical Phenomena at Nanoscale
Conor J. McCluskey, Niyorjyoti Sharma, Jesi R. Maguire +9
Kelvin probe microscopy (KPFM) is a well-established scanning probe technique, used to measure surface potential accurately; it has found extensive use in the study of a range of m…
Nanoelectromechanics of Polarization Switching in Piezoresponse Force Microscopy
Sergei V. Kalinin, A. Gruverman, J. Shin +3
Nanoscale polarization switching in ferroelectric materials by Piezoresponse Force Microscopy (PFM) in weak and strong indentation limits is analyzed using exact solutions for elec…
