Position of Fermi level in the semiconducting material
Posted: Sun May 29, 2022 2:04 am
Dear Experts,
I have one doubt about the position of the Fermi level in semiconductors. I plotted the band structure of one 2D material having a band gap ~1.24 eV. I am getting the Fermi level in the middle of the valance and conduction bands. But I noticed in the literature that the Fermi level is coming on the top of the Valance band in the band structure plot for the same material (using the VASP code only).
Which one is the correct way of representing the band structure plot? If the second way is correct then how can I chage my Fermi level.
Please give your helpful suggestions about it.
