Boffins have another idea to replace silicon

Just when you thought one of the others might actually get used

Stanford University boffins have emerged from their smoke-filled labs with yet another replacement for silicon in processes.

It seems like we get one of these every few months, with none of them ever actually being used.

This time it is two semiconductor materials, namely hafnium diselenide and zirconium diselenide, that not only are similar to silicon in many regards but also solves its biggest drawback: they can be made thinner.

Thanks to their high-k dielectric nature, the researchers could make functional circuits with these materials that are only three atoms thick. As a result, they need less energy for switching, making them more efficient than their silicon based counterparts.

One of the boffins who goes by the name Eric Pop said that silicon won’t go away.

“But for consumers, this could mean much longer battery life and much more complex functionality if these semiconductors can be integrated with silicon.”

Even if the chip industry says that it will opt for this way to beat Moore’s Law instead of things like graphene it will probably be years before this technology becomes mainstream.
