To tune the graphene fermi level, In the real implementation, a practical method how to control Fermi level of graphene based polarization converter?
Hello Muhammad Sajjad ,
To change the Fermi level in any material you need to modify the number of electrons (since the Fermi level is the energy at which all the electrons are accounted for in the material). In practice this can be achieved at least two ways. First, one could experimentally gate the material (that is, supplying an external voltage and thus changing the electron occupation of the system). Or 2) by chemically modifying the sample. For example, one could use absorbed atoms to modify the chemical environment and thus change the number of electrons.
