Material after Silicon

[AleksandarK]

I was wondering, what material will be used after silicon, when we hit its limitations.

Maybe go 3D with silicon?

GaAs or GaN, potentially on top of silicon carbide, seems to be a thing that already sees some use w/ alot of the hard work already having been done.
