Landau Theory For Shape Memory Polycrystals
Rajeev Ahluwalia, Turab Lookman, Avadh Saxena +1
We propose a Ginzburg-Landau theory for the elastic properties of shape memory polycrystals. A single crystal elastic free energy for a system that undergoes a square-to-rectangle…
Electronic properties of structural twin and antiphase boundaries in materials with strong electron-lattice couplings
K. H. Ahn, T. Lookman, A. Saxena +1
Using a symmetry-based atomic scale theory of lattice distortions, we demonstrate that elastic textures, such as twin and antiphase boundaries, can generate intricate electronic in…
Electromechanical Properties of Multi-Domain Ferroelectrics
Rajeev Ahluwalia, Turab Lookman, Avadh Saxena +1
We study theoretically the influence of the underlying domain microstructure on the electromechanical properties of ferroelectrics. Our calculations are based on a continuum approa…
Elasticity-driven Nanoscale Texturing in Complex Electronic Materials
A. R. Bishop, T. Lookman, A. Saxena +1
Finescale probes of many complex electronic materials have revealed a non-uniform nanoworld of sign-varying textures in strain, charge and magnetization, forming meandering ribbons…
