When the Fermi level is shifted to the nearby van Hove singularity by electron doping from its intrinsic position, the ZT value (figure of merit) of the high-buckled plumbene at 100 K is increased by about 250 times.

The formation of fullerene carbon nanobuds (CNBs) on carbon nanotube (CNT) caps is energetically more favorable than that on CNT sidewalls. Generally, CNBs based on CNT ends can induce resonant transmissions near the Fermi level.

A proper adoption of the n- or p-type dopants allows for the modulation of the work function, the Fermi level pinning, the band bending, and the photo-adsorbing efficiency near the InSe surface/interface.

The Li ion enhances the VCH induced magnetism. The −1 charge doping shifts the Fermi level to the CBM further increasing magnetism. The +1 charge doping shifts the Fermi level to the VBM reducing magnetism.
