The crystal has a lattice parameter of 0.541 nm. The crystal structure is also known as diamond cubic and may be thought of as two interpenetrating fcc lattices, one for sulphur the other for zinc, ...

The basis is two ions, a sodium cation and a chlorine anion. The crystal lattice parameter is 0.563 nm. The diagram shows both a unit cell with ion locations indicated (a) and a space filling model (b ...

RECENTLY, with the increase of the resolving power of the electron microscope, it has become possible to make a direct observation of a crystal lattice composed of large molecules. J. W.

Laser diodes are semiconductors that generate light and amplify it using repeated reflection or "optical feedback." Once the ...
