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…
Direct Thermal Imaging of Domain Wall Hot Spots in LiNbO3
Lindsey R. Lynch, J. Marty Gregg, Amit Kumar +2
Ferroelectric domain wall devices offer a promising route to low-voltage, reconfigurable nanoelectronics by confining currents to nanoscale conducting interfaces within an insulati…
Current Flow Mapping in Conducting Ferroelectric Domain Walls using Scanning NV-Magnetometry
Conor J. McCluskey, James Dalzell, Amit Kumar +1
The electrical conductivity of parallel plate capacitors, with ferroelectric lithium niobate as the dielectric layer, can be extensively and progressively modified by the controlle…
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…
