Controlled introduction of extrinsic defects is a common strategy for engineering the properties of semiconductors and insulators. For instance, doping TiO2 nanoparticles with nitrogen atoms ...

Vacancy-type point defects, i.e., defects where one or several atoms are missing from a lattice site, are often present in rather high concentrations in semiconductors and insulators due to their ...

The core is often surrounded by a shell of a different semiconductor material with a wider bandgap, such as zinc sulfide (ZnS) or cadmium sulfide (CdS). This core-shell structure helps passivate the ...

overcame this challenge by employing "magic-sized clusters" made from cadmium-based semiconductor compounds. Magic-sized clusters are unique nanoparticles because they are identical copies of each ...
