在這篇論文之中，我們以緊束模型研究以鋸齒狀切割之一維雙層奈米石墨帶
在各種磁場下的電子的能帶結構及態密度。我們使用各種外加磁場與兩種石墨
帶寬度，看到了許多相應的物理量產生變化。外加磁場會造成準藍道能階的出
現，而石墨帶寬度影響到準藍道能階以否產生。
另外，我們也發現了一維雙層奈米石墨帶與一維單層奈米石墨帶的與多不同
性質。包括價帶與導帶中能帶階分成兩群，以費米能為中心上下不對稱，準藍
道能階對磁場的關係與費米能附近的平坦能帶會打開成兩條等。

In this thesis, the magnetoelectronic properties of the AB-stacked bilayer zigzag
graphite nanoribbon are investigated by the tight-binding model. By changing the
external magnetic field or the width of the nanoribbon, we could see some changes in
band structure and density of states. The appearance and the width of the
quasi-Landau level in band structure are controlled by the external magnetic field and
the width of the nanoribbon.
We also found some differences between monolayer and bilayer AB-stacked
zigzag graphite nanoribbon. For bilayer AB-stacked zigzag graphite nanoribbon :
There are two groups of parabolic energy bands in conduction and valence bands.
There is no symmetry to EF=0 between conduction and valence bands. There are two
partial flat bands which is caused by the interactions between layers.
