| It is an important semiconductor and is used to make devices such as microwave frequency integrated circuits, infrared LEDs,
laser diodes and solar cells.

|
| GeAs has some electronic properties which are superior to silicon's, these allow it to function at frequencies greater than 250GHz, and generate less noise than silicon devices when operated at higher frequencies. GeAs is also capable of emitting light, silicon is very poor at emitting light.
