Half the band gap of silicon, 10 times the mobility, at room temperature… sounds like it would be able to switch up to 20 times faster in the same conditions.
I can’t read the full paper, but what I’d wonder is how those values change with temperature:
0.6eV at 300K is similar to Germanium, which has slightly lower mobility but has been successfully used in semiconductors. If graphene has a better dimensional stability (as in, doesn’t grow random dendrites over time), then it could be a decent improvement.

wait, last time i’ve checked if you want fast switching, faster than silicon can get you, you use GaN, and it has 3.4eV band gap. how does it work?
