摘要

The effects of the modulated magnetic field on one dimension at energy bands of nanographite ribbons are investigated by the Peierls tight-binding model. Electronic properties strongly depend on the strength and the period of the modulated magnetic field, the ribbon width, and the edge structure. The modulated magnetic field could destroy state degeneracy, modify energy dispersions, alter subband spacings, affect wave functions, create additional band-edge states, and cause semiconductor-metal transitions. The main features of energy bands are directly reflected in density of states, such as the number, the positions, the heights, and divergent structures of the prominent peaks.
