Strong interaction between plasmon and topological surface state in Bi₂Se₃/Cu_2-<i>x</i>S nanowires for solar-driven photothermal applications.

ABSTRACT: Developing high-performance photothermal materials and unraveling the underlying mechanism are essential for photothermal applications. Here, photothermal performance improved by strong interaction between plasmon and topological surface state (TSS) is demonstrated in Bi₂Se₃/Cu_2-xS nanowires. This hybrid, which Cu_2-xS nanosheets were grown on Bi₂Se₃ nanowires, leverages the plasmon resonance and TSS-induced optical property, generating wide and efficient light absorption. A series of tests reveals the strong resonance coupling, TSS-induced hot electron injection, and plasmon-induced hot hole relaxation within the hybrids, endowing the Bi₂Se₃/Cu_2-x</
