摘要

For more than 20 years many millions of dollars have been spent for the growth of gallium arsenide and other hetero-materials on silicon for all the obvious reasons, larger, cheaper and higher quality substrates available in quantity (mostly elemental Groups Ⅲ-Ⅴ and Ⅱ-Ⅵ). Unfortunately most of it was spent producing either little success or a cost in excess of the competing compound semiconductor substrate. And, for some time the only compound semiconductor that showed promise was silicon-germanium, which does not quite present the same technology challenge, since both elements are in the same Group IV of the Periodic Table and therefore the silicon-germanium material system may be classed as an alloy rather than a compound.
