band gap | minimum energy that must be added to a valence electron held within a semiconductor crystal lattice to permit it to become a conduction electron able to move freely throughout the crystal |
CMOS | complementary metal oxide semiconductor |
COTS | commercial off the shelf |
GaAs | gallium arsenide |
GaN | gallium nitride |
HT | high temperature |
HTE | high-temperature electronics |
semi-conductor | Any of a class of solids (as germanium or silicon) whose electrical conductivity is between that of a conductor and that of an insulator. Conductivity is nearly as great as a metal at high temperatures and nearly absent at low temperatures. |
Si | silicon |
SiC | silicon carbide |
SOI | silicon on insulator |
system on a chip | Has generally meant integrating all the functions at the board level containing the current generation of chips. (Since the emergence of the first integrated circuits in the '60s, engineers have planned chips with more functions on them. They've called the next level of integration some variation of the term system on a chip.) |
