Summary: An ultracompact graphene-coated twisted silica taper is fabricated and applied for highly sensitive sensing and all-optical modulation. The coated graphene enhances the temperature sensing by its fast thermal response and the production and confinement of more propagating modes through the surface plasmon polariton (SPP) effect in the twisted taper. The enhanced multimode interference improves the optical sensitivities for temperature and strain sensing. Additionally, the proposed taper exhibits a significant resonant wavelength shift for all-optical modulation.

Summary: This work reports the attractive performance of perovskite photoconductors based on epitaxial CsPbBr3-Pb4S3Br2 Janus nanocrystals, as well as the carrier relaxation and transfer mechanism of the heterojunction. By combining transient optical absorption and quantum dynamics simulation, it is demonstrated that the photogenerated holes on CsPbBr3 can be successfully extracted by Pb4S3Br2, with hole transfer proceeding about three times faster than energy loss and remaining hot for about 300 fs. This feature favors long-range charge separation and transport, resulting in exceptional responsivity (34.0 A W-1) and specific detectivity (1.26 x 1014 Jones) of the Janus nanocrystal photoconductors.

Summary: This study reports the synthesis of uniform, epitaxially grown CsPbBr3/CdS Janus nanocrystal heterostructures with ultrafast charge separation across the electronically coupled interface. Each Janus nanocrystal contains a CdS domain that grows exclusively on a single {220} facet of CsPbBr3 nanocrystals. The promoted charge separation and extraction in epitaxial Janus nanocrystals leads to photoconductors with drastically improved responsivity and detectivity, which is promising for ultrasensitive photodetection.

Summary: In this study, a ternary heterostructure PVDF/ZnO/Au (PZA) nanobrush photocatalyst with high piezo-photocatalytic efficiency was synthesized. Under both solar and mechanical energy, the PZA nanobrush exhibited significantly increased catalytic degradation rate compared to solar alone and mechanical energy alone. The high piezo-photocatalytic activity of PZA nanobrush can be attributed to the surface plasmon resonance (SPR) coupling of Au and the built-in electric field from ZnO and PVDF.
