A way of life available for organisms which are physically, ecologically, and evolutionarily equipped to live it; such as, "catching insects in the air at night".

Same as cell barrier.

The term derives from the fact that this microscopically thin region is depleted of charge carriers (free electrons and hole).

A method of growing a large-size, high-quality crystal whereby coils heat a polycrystalline ingot placed on top of a single-crystal seed.

As the coils are slowly raised the molten interface beneath the coils becomes single crystal.
