| Summary: | 碩士 === 國立成功大學 === 物理學系碩博士班 === 93 === Electronic structures of single-walled BC3 nanotubes are calculated by the nearest-neighbor tight-binding model. Electronic properties are significantly affected by the parallel magnetic field and the perpendicular electric field,these two fields destroy state degeneracy, change energy dispersions or subband curvatures, and produce or alter edge states. The semiconductor-metal transition is induced by the transverse electric field, but not the longitudinal magnetic field. All BC3 nanotubes exhibit the paramagnetic behavior at small magnetic field. The magnetic response of zigzag BC3 nanotubes is much higher than that of armchair BC3 nanotubes. There are certain important differences between BC3 nanotubes and carbon nanotubes in electronic and magnetic properties.
