Gallium indium arsenide antimonide phosphide
Encyclopedia
Gallium indium arsenide antimonide phosphide ( or GaInPAsSb) is a semiconductor material.
Research has shown that GaInAsSbP can be used in the manufacture of mid-infrared light-emitting diode
s and thermophotovoltaic
cells.
GaInAsSbP layers can be grown by heteroepitaxy on indium arsenide, gallium antimonide and other materials. The exact composition can be tuned in order to make it lattice matched
. The presence of five elements in the alloy allows extra degrees of freedom, making it possible to fix the lattice constant while varying the bandgap.

Lattice constant
The lattice constant [or lattice parameter] refers to the constant distance between unit cells in a crystal lattice. Lattices in three dimensions generally have three lattice constants, referred to as a, b, and c. However, in the special case of cubic crystal structures, all of the constants are...
