Giant Apparent Flexoelectricity in Semiconductors Driven by Insulator-to-metal Transition
Ya-Xun Wang, Jian-Gao Li, Gotthard Seifert +2
We elucidate the flexoelectricity of materials in the high strain gradient regime, of which the underlying mechanism is less understood. By using the generalized Bloch theorem, we…

The Phonon Quasiparticle Approach for Anharmonic Properties of Solids
Zhen Zhang, Dong-Bo Zhang, Tao Sun +1
Knowledge of lattice anharmonicity is essential to elucidate distinctive thermal properties in crystalline solids. Yet, accurate \textit{ab initio} investigations of lattice anharm…

Transversal Flexoelectricity of Semiconductor Thinfilm under High Strain Gradient
Chao He, Jin-Kun Tang, Yang Yang +2
The flexoelectric behaviors of solids under high strain gradient can be distinct from that under low strain gradient. Using the generalized Bloch theorem, we investigate theoretica…
