Designing multiple charge carrier separation pathways in core-type near infrared colloidal nanocrystal for broadband photodetector.

ABSTRACT: Near-infrared colloidal nanocrystals (NIR-CNCs) have been widely utilized in optoelectronic applications due to their exceptional optical properties and suitability for mass production. However, their practical application is often hindered by poor chemical stability and suboptimal electronic properties. In this work, four different surface ligand systems-insulating ligands, organic molecular linkers, inorganic molecular linkers, and matrix-type ligands-were systematically investigated to evaluate their effects on the transport and recombination behavior of NIR-CNCs via photoinduced carriers. While molecular linkers enhance transport behavior by improving electronic coupling, they tend to induce photoinduced charge carrier accumulation under AM1.5 illumination due to a high degree o
