Tuning colloidal quantum dot band edge positions through solution-phase surface chemistry modification

Tuning colloidal quantum dot band edge positions through solution-phase surface chemistry modification

The band edge positions of semiconductors decide their optoelectronic properties. Here, the authors establish a simple ligand exchange strategy to tune the band edge positions of colloidal PbS semiconductor quantum dots, revealing clear relationships between surface chemistry and band edge position.
