摘要:

在这项工作中,我们研究了石墨烯系统中的电子和声子的对称性作为层数的函数。我们推导出了布里渊区中所有点的电子辐射和电子-声子相互作用的选择规则。通过考虑这些选择规则,我们解决了双共振拉曼散射过程。单层和双层石墨烯在施加电场的存在下进行了讨论。

英文摘要:

In this work we study the symmetry properties of electrons and phonons in graphene systems as function of the number of layers. We derive the selection rules for the electron-radiation and for the electron-phonon interactions at all points in the Brillouin zone. By considering these selection rules, we address the double resonance Raman scattering process. The monolayer and bilayer graphene in the presence of an applied electric field are also discussed.
