Germanium displaces silicon
 

Chips today use complementary metal oxide semiconductor (CMOS) based on purified silicon substrates to do their magic work.

But scientists at Purdue University claim to have created the first modern germanium circuit that cuts silicon out of the equation.

The first transistor, created by Bell Labs, used purified germanium cooked up in the Purdue labs in 1947.
