Zinc sulphide exists with two different crystal structures, the cubic zinc blend (top diagram) and the hexagonal Wurtzite (lower diagram). In the zinc blend structure the sulphur ions form an fcc ...

The aim is to produce zinc sulfide crystals doped with copper impurities. This creates a phosphor with a familiar green glow. [Hydrogen Time] starts by noting that it’s important to make sure ...

will occupy the latice points that define the face centered cubic unit cell, with the zinc ions occupying the tetrahedral holes. Since there are four sulfide ions (FCC), we need only four zinc ions to ...

Semiconductor nanoparticles typically consist of a crystalline core made from a semiconductor material ... of a different semiconductor material with a wider bandgap, such as zinc sulfide (ZnS) or ...

Researchers have found a way to increase the number of molecules that adhere to the surface of small nanocrystals. A team at ...
