Considering the strong built-in electric field (BEF) induced by the spontaneous and piezoelectric polarizations and the intrasubband relaxation, we investigate the linear and nonlinear intersubband optical absorptions in In x Ga 1 - x N/Al y Ga 1 - y N strained single quantum wells (QWs) ...
Furthermore, the charge redistribution around the heterointerfaces create built-in electric field (BEF) and produce beneficial changes in the energy conversion process [27]. Therefore, designing paper-like flexible electrode with a multitude of heterogeneous surfaces is crucial. Herein, we designed and...
On this basis, WC and Co on nitrogen‐doped carbon (WC‐Co@NC) with an interfacial built‐in electric field (BEF) is designed as an ORR catalyst. The theoretical calculation certifies that the BEF of W─C─Co connections promote charge separation and directional migration, thus realizing the...
