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…

Flat Bands in Twisted Bilayers of Two-Dimensional Polar Materials
Xing-Ju Zhao, Yang Yang, Dong-Bo Zhang +1
The existence of Bloch flat bands provides an facile pathway to realize strongly correlated phenomena in materials. Using density-functional theory and tight-binding approach, we s…
