I read a book a while back called "the disappearing spoon" where it discussed how earlier semiconductors used gallium, but were failure prone due to the heat (gallium has a very low melting temperature). Silicon was a godsend and once that was used, it changed semiconductors forever.
My first thought after reading the summary was "oh no! Not this again!" But the "nitrade" may make a huge difference. Hopefully this is the case.
