Microstructural Evolution of Charged Defects in the Fatigue Process of Polycrystalline BiFeO3 Thin Films
Qingqing Ke, Amit Kumar, Xiaojie Lou +4
Fatigue failure in ferroelectrics has been intensively investigated in the past few decades. Most of the mechanisms discussed for ferroelectric fatigue have been built on the "hypo…
Layer-dependent Band Alignment and Work Function of Few-Layer Phosphorene
Yongqing Cai, Gang Zhang, Yong-Wei Zhang
Using first-principles calculations, we study the electronic properties of few-layer phosphorene focusing on layer-dependent behavior of band gap, work function and band alignment…
Strong Thermal Transport Anisotropy and Strain Modulation in Single-Layer Phosphorene
Zhun-Yong Ong, Yongqing Cai, Gang Zhang +1
Using first-principles calculations and non-equilibrium Green's function method, we investigate the ballistic thermal transport in single-layer phosphorene. A significant crystallo…
