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 ...

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 ...

Semiconductor science and technology is the art of defect engineering. The theoretical modeling of defects has improved dramatically over the past decade. These tools are now applied to a wide range ...

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 ...

TASS/. The Siberian Federal University (SFU) scientists, together with colleagues from Russia, Sweden and the US, studied the defects that occurs in arrays of silicon nanoparticles (nanogrids ...
