| 英文摘要 | spatially resolved surface photovoltage spectroscopy (srsps) was employed to obtain direct evidence for highly anisotropic photogenerated charge separation on different facets of a single bivo4 photocatalyst. through the controlled synthesis of a single crystal with preferentially exposed {010} facets, highly anisotropic photogenerated hole transfer to the {011} facet of single bivo4 crystals was observed. the surface photovoltage signal intensity on the {011} facet was 70 times stronger than that on the {010} facets. the influence of the built-in electric field in the space charge region of different facets on the anisotropic photoinduced charge transfer in a single semiconductor crystal is revealed. |
