Hi, I'm studying graphene nowadays with paper
"Electric Field Effect in Atomically Thin Carbon Films" .
In this paper, there is a description about the linear dependence btw the fermi energy and SdHO frequency in Fig.3 and Supplementary information.
Specifically, in supplementary information, there is a formula below ( I uploaded )
Is there anyone who knows where this formula came from?
I couldn't find any clue for this.
Thanks for reading this! :)
