I have computed real and Imaginary part of electron self energies.
I have used real of electron self-energies to renormalize the Kohn-Sham eigenvalues (Rev. Mod. Phys. 2017, 89, 015003).
I have observed that the valence bands shift upwards, while conduction bands shift downwards due to the renormalization.
Can you help me to understand why temperature effects decrease (or stabilize electrons) energy of electrons, whereas increase the holes energies?
I will be grateful for this.
