FermiWavenumber

graphenemodeling.graphene.monolayer.FermiWavenumber(FermiLevel, model, g0prime=0.0)

The Fermi wavenumber, i.e. the wavenumber of the state at the Fermi energy.

Parameters:

• FermiLevel (array-like, J) – Fermi level
• model (string) – ‘LowEnergy’ or ‘FullTightBinding’.

Examples

Confirm energy of Fermi wavevector is equal to Fermi level.

>>> from graphenemodeling import graphene
>>> from scipy.constants import elementary_charge as eV
>>> mlg = graphene.Monolayer()
>>> FermiLevel = 0.4 * eV
>>> kF = mlg.FermiWavenumber(FermiLevel, model='LowEnergy')
>>> mlg.CarrierDispersion(kF,model='LowEnergy')/eV
0.4
