多層AB堆疊石墨烯，其能帶結構與光學性質可用緊束模型(tight-binding model)及梯度近似(gradient approximation)來作計算。對於一個n_L層的AB堆疊石墨烯，在中能和低頻區會有n_L^2個激發通道。然而，在激發譜裡，偶數層(奇數層)在中能區有一個肩膀結構及n_L個尖峰，在低頻則存在n_L(n_L-1)個峰。隨著層數的增加至n_L層，其結構可在特定區間被找到，且奇數層與偶數層之間的電子結構和光學性質的差異性會降低。當層數增至30(30)層時，其二維AB堆疊石墨烯的光譜在中能(低頻)區幾乎與三維AB堆疊石墨烯相同。

The band structures and optical properties of AB-stacked multilayer graphenes (MLG) are calculated by the tight-binding model and gradient approximation. For a n_L-layer AB-stacked graphenes, there are about n_L^2 of the excitation channels at both low and middle frequencies. However, in the excitation spectra, n_L (n_L-1) peaks exist at low frequencies for even-layer (odd-layer) systems, and one shoulder and n_L peaks at middle frequency. With increasing n_L, those structures are confined to certain boundaries, and the differences in the electonic structures and optical properties between the odd and even layers are reduced. When n_L grows to 30 (30), the spectra of 2D AB-stacked graphene are almost identical to those of 3D AB-stacked graphite at middle (low) frequencies.
