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 ...

By varying crystal growth and processing conditions, the effects of crystalline defects and impurities at surfaces, interfaces and in the bulk semiconductor can be investigated and often enhanced or ...

Unlike metals or even other doped semiconductors ... these particles generate plasmons that produce specific colors. Gold nanoparticles appear ruby red, while silver nanoparticles display a ...
