| 英文摘要 | Bulk photovoltaic effect, i.e. shift current, is a nonlinear second-order optical response that can rectify an alternating current (AC) electric field into a direct current (DC). Depending on the wavelength of the incident light, shift current finds applications in various fields, including solar energy conversion and radiation detection. Its promising application in energy conversion and information processing has inspired investigations to uncover the relationship between shift current and electronic structures of materials. Despite numerous efforts dedicated to designing principles for strong bulk photovoltaic effect materials, the only widely accepted crucial parameter is the joint density of states (JDOS). In this study, employing effective model analysis and first-principles calculations, an enhancement effect of bulk photovoltaic effect is found to arise from band hybridization that is typically along with anti-crossing-like electronic band structures, similar to the Berry curvature effects in intrinsic anomalous Hall conductivity. While this mechanism does not offer a comprehensive understanding of the relationship between electronic structure and the magnitude of bulk photovoltaic effect, it represents practical progress in the design of materials with strong bulk photovoltaic effect. This work reveals that the band hybridization of material can serve as a universal mechanism for enhancing non-linear photocurrent based on both model and realistic material study. This improved understanding provids another practical guiding principle for designing high-performance nonlinear optical materials other than the joint density of states. image |
