Enhanced voltage of the dynamic homojunction generator based on the N-i-N structure. (a) Schematic illustration of the dynamic N-Si/insulator/N-Si junction. (b) Band diagram and carrier dynamic process of the dynamic N-Si/insulator/N-Si junction generator. (c) curves of the dynamic N-Si/N-Si junction generator with and without SiO2. (d) One-dimensional band alignment of the energy band structure for silicon with various dielectric layers (ZnO, HfO2, and Al2O3). (e) The increased of the dynamic N-Si/dielectric/N-Si junction generator with different Interfacial barrier heights.
