Question
Dear Kevin

Can Gallium Arsenide replace Silicon, Germanium and Carbon as semiconductors in the future?.

Thanks
Prashant

Answer
Hi Prashant,

Probably not. Semiconductors have a range of properties, including cost, which means that the one that performs best is chosen. GaAs semiconductors are widely used in micro-wave applications because of their electronic properties. Silicon is very cheap and plentiful and does not suffer from end of life toxicity problems.

This is just my view.

Best wishes.
Kevin
