Anomalous Residual Surface Conductivity in a Superconductor with Strong Spin-Orbit Coupling
J. R. Chamorro, P. Chauhan, C. Sun +10
Conventional BCS superconductors are expected to exhibit a conductivity with vanishing dissipation with decreasing temperature. While bulk physical properties measurements indicate…
Influence of space charge on domain patterns and susceptibility in a rhombohedral ferroelectric film
Wei Li Cheah, Nathaniel Ng, Rajeev Ahluwalia
The presence of a space charge region induces an internal electric field within the charged region that, in a ferroelectric material, would rotate the polarisations to align with t…
Electron-Beam Driven Relaxation Oscillations in Ferroelectric Nanodisks
Nathaniel Ng, Rajeev Ahluwalia, Ashok Kumar +3
Using a combination of computational simulations, atomic-scale resolution imaging and phenomenological modelling, we examine the underlying mechanism for nanodomain restructuring i…
Current-induced switching of magnetic tunnel junctions: Effects of field-like spin-transfer torque, pinned-layer magnetization orientation and temperature
R. K. Tiwari, M. H. Jhon, N. Ng +2
We study current-induced switching in magnetic tunnel junctions (MTJs) in the presence of a field-like spin-transfer torque and titled pinned-layer magnetization in the high curren…
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…
Depletion layer-induced size effects in ferroelectric thin films: A Ginzburg-Landau model study
Nathaniel Ng, Rajeev Ahluwalia, David J. Srolovitz
A Ginzburg-Landau model is used to demonstrate how depletion layers give rise to thickness-dependent ferroelectric properties in thin films. It is shown that free charge layers at…
Lateral Size and Thickness Dependence in Ferroelectric Nanostructures Formed by Localized Domain Switching
Nathaniel Ng, Rajeev Ahluwalia, Haibin Su +1
Ferroelectric nanostructures can be formed by local switching of domains using techniques such as piezo-force microscopy (PFM). Understanding lateral size effects is important to d…
