Abstract

Layered graphene systems are among the mainstream materials [1-19] owing to their various crystal symmetries. Modifying the number of layers, stacking configuration and external fields can lead to diverse phenomena [3, 20], e.g., easy modulation of vertical optical transitions. There are a number of theoretical [20-39] and experimental studies [40-57] on few-layer graphene systems. Their main focus is on low-frequency absorption structures in the presence/absence of gate voltage and magnetic field. Specifically, the magneto-optical theory is developed through the generalized tight-binding model based on the two sublattices of each honeycomb crystal. Systematic investigations for diversified magnetic quantization have been done for 2D materials [20, 21], such as the unusual Landau levels and magneto-optical selection rules. This theoretical framework is useful in fully understanding the electronic [1, 2], magnetic [21, 40], optical [20-23, 40-44], transport [58] and Coulomb-excitation [59] properties under intrinsic atomic interactions and field perturbations. However, the Kubo formula is not enough for exploring the reflectance and transmittance spectra of thin films with prominent boundary effects. In this work, an optical scattering model is developed within the previous framework. The calculated results could be examined through highresolution optical measurements [40-57]….
