Abstract

We synthesized a heterotetrapod composed of a chalcopyrite(ch)-CuInS₂ core and wurtzite(w)-CdS arms and elucidated its optical properties and light-stimulated carrier dynamics using fs-laser flash photolysis. The CuInS₂/CdS heterotetrapod possessed quasi-type II band alignment, which caused much longer-lived charge separation than that in the isolated CuInS₂ nanocrystal.
