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 ...

We now apply the group theoretical notations to the electron energy band structure of the diamond- and zinc-blende-type semiconductors. Since the electrons move in the presence of a crystal potential, ...

Hexagonal close packing is one of two crystal structures that derive from stacking close-packed-planes of hard sphere atoms. In the HCP structure only two stacking ...

Researchers developed a bifocal lens based on two layers of liquid crystal (LC) structures. The intensities for the two focal lengths can be easily adjusted by applying external voltage.

A crystal radio is basically a high Q resonator tied to an antenna and an envelope detector. These days the envelope detector is a point contact diode such as a 1N34 Germanium diode. The resonant ...

Report by BC Professor of Physics David Broido and international colleagues confirm high thermal conductivity predicted for isotopically enriched cubic boron nitride Research by Professor of Physics ...

More than 4,000 naturally occurring minerals—inorganic solids that have a characteristic chemical composition and specific crystal structure—have been found on Earth. They are formed of simple ...

LONDON, Oct 9 (Reuters) - The global zinc market is facing a sizeable supply deficit in 2024 as a raw materials squeeze forces smelters to reduce production of refined metal. The International ...

Crystal Raypole’s work appears on Healthline, and she’s previously worked as a writer and editor for GoodTherapy. Her interests include Japanese language and translation, cooking, natural ...

The lenses, which use two layers of liquid crystal structures, could be useful for various applications such as optical interconnections, biological imaging, augmented/virtual reality devices and ...
