[Pw_forum] Need to find V-I characteristics of Graphene.

[siddheshwar chopra]

Dear All,
I read some research works on V-I characteristics of Graphene based
nanoelectronic devices. I cam to know that QE was used to determine
Transmission coefficients for different energies. And then NanoTCad Vides
etc. packages were used to find V-I curve. Why is it so? Can't we get
current directly using QE (using Landauer Buttiker formula)?
Somebody please clarify this point, so that we can get started with
learning this.

Regards,
