Title: perpendicular electricfield
Post by: Val on March 7, 2011, 05:30

sir, 
    could you help me how to apply the perpendicular electric field to the bi-layer or trilayer graphene .how to shift the fermi level for the same.

The electric field in term of the description of dipole correction or saw-tooth potential is not implemented. To consider the electric filed perpendicular to the graphene, you may use the applied bias voltage in a two-probe system, in which the normal direction of bi-layer or trilayer of graphene is parallel to the transport direction (i.e. z direction) of such two-probe system. Also you can use the applied gate voltage, while in this case, the normal direction of graphene layer should be perpendicular to the transport direction.

The related topic can be found this thread: https://forum.quantumatk.com/index.php?topic=1039.0

By introducing the hole or electron doping (e.g., boron or nitrogen impurities in graphene), the Fermi level of graphene can be shifted.

The link here does not exist.
Can you direct to the current link?

Since changing domain, these old links don't work and there is no simple way to fix all of them automatically.

However, whenever you encounter links like this, just replace quantumwise.com/forum by forum.quantumatk.com (and use https)
You can also just replace the topic=XXXX in the URL of the page you are currently watching with the topic of relevance (1039 in this case)

So in this case, it's https://forum.quantumatk.com/index.php?topic=1039.0
