Gallium
Gallium arsenide has a similar structure to silicon and is a useful silicon substitute for the electronics industry. It is an important component of many semiconductors. It is also used in red LEDs (light emitting diodes) because of its ability to convert electricity to light. Solar panels on the Mars Exploration Rover contained gallium arsenide.

Gallium arsenide is used in LEDs. It is a semiconductor. Like silicon it has the lattice of diamond. Every atom is evenly surrounded by 4 neighbours. It is connected to each of them by a pair of electrons. In GaAs arsen gives 5 electrons and gallium 3 to the 4 bonds. Bonding orbitals are not symetrical as Ga atoms are slightly bigger then arsenic …
