Current density in graphene-giant?

Hi,

I just read a paper on graphene's basic properties and it says that since current density J is given as

J=q*n*v

where q is the elementary charge, n is the electron density and v is the Fermi velocity of electrons and for graphene n=6*10^12 cm^-2 and v=10^8 cm/s, the current density in graphene is giant as J=100A/cm. It doesn't sound right. Is it a realistic value for J? Or what can I do to correctly interpret this?

Thanks.

I'm sorry you are not generating any responses at the moment. Is there any additional information you can share with us? Any new findings?

Bumping this because I'm interested in the answer too. (Will be starting a project with graphene soon)

Also, if anyone replies - is there an intuition behind graphene's basic properties? Right now I'm not really getting why graphene is the way it is.
