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…
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…
Electron-hole coexistence in disordered graphene probed by high-field magneto-transport
J. M. Poumirol, W. Escoffier, A. Kumar +3
We report on magneto-transport measurement in disordered graphene under pulsed magnetic field of up to 57T. For large electron or hole doping, the system displays the expected anom…
