> I never thought electron drift velocity could be 1E6 m/s. That's wild. GaAs, InP, and InAs have measured max electron velocities in the ballpark of 300,000 m

> I never thought electron drift velocity could be 1E6 m/s. That's wild. GaAs, InP, and InAs have measured max electron velocities in the ballpark of 300,000 m/s, which is ~ 1/1000 of c. So they're listing graphene at around 3x of pretty standard III-V materials. (It's a nice improvement in speed, but building good electronic devices involves much more than electron velocity.)
