Temperature affects the electron gas density and energy level filling differently across materials featuring different types of conductivity. Although, in metallic systems, temperature slightly Please note the decrease in amplitude with increasing magnetic field intensity. Reprinted with permission from the work by Yin et al. broadens the energy levels near the Fermi surface, it has only a minimal effect on the electron gas density. On the other hand, in semiconductors, it significantly increases electron density by promoting electrons from the valence to the conduction band. For graphene, the electron-hole pair generation should slightly increase with higher temperatures. Finally, in the case of long conjugated molecules, one would expect temperature-dependent orbital populations.
