Silicon is the king of the computing world. Almost all commercial integrated circuits have been based on silicon and, for the most part, on a single basic process called complementary metal oxide (CMOS).
But the end of silicon may be in sight. Even industry giant IBM acknowledges that silicon’s days are numbered. But why? And what’s going to replace it?
There is a whole raft of new materials and partial replacements for silicon in the offing. Let’s take a look at why it’s dominant and what materials may eventually knock silicon (and germanium) out of the hot seat.
