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…
Probing frustrated metallo-molecular spin Kondo lattice interfaces through anomalous Nernst effect
Servet Ozdemir, Matthew Rogers, Conor J. McCluskey +7
Frustrated Kondo spin lattice (KSL) systems away from the antiferromagnetic (AFM) ground state have been found to display strange metal behaviour. A signature of strange metals in…
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…
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…
Ferroelectric Domain Wall Logic Gates
Ahmet Suna, Conor J. McCluskey, Jesi R. Maguire +3
Fundamentally, lithium niobate is an extremely good electrical insulator. However, this can change dramatically when 180° domain walls are present, as they are often found to be st…
Imaging Ferroelectrics: Charge Gradient Microscopy (CGM) versus Potential Gradient Microscopy (PGM)
Jesi R. Maguire, Hamza Waseem, Raymond G. P. McQuaid +3
In 2014, Charge Gradient Microscopy (CGM) was first reported as a new scanning probe imaging mode, particularly well-suited for the characterisation of ferroelectrics. The implemen…
Influence of charged walls and defects on DC resistivity and dielectric relaxation in Cu-Cl boracite
C. Cochard, T. Granzow, C. M. Fernandez-Posada +5
Charged domain walls form spontaneously in Cu-Cl boracite on cooling through the phase transition. These walls exhibit changed conductivity compared to the bulk and motion consiste…
Manipulating Ferroelectric Domains in Nanostructures Under Electron Beams
Rajeev Ahluwalia, Nathaniel Ng, Alina Schilling +5
Freestanding BaTiO3 nanodots exhibit domain structures characterized by distinct quadrants of ferroelastic 90° domains in transmission electron microscopy (TEM) observations. These…
