摘要：
四层石墨烯最近成为具有多功能电子性质的少层石墨烯家族的新成员。这种材料可以以三种不同的堆叠构型实现，我们确定了其在角分辨光电子能谱（ARPES）、动态光学电导率以及带间激发的拉曼光谱中的光谱特征。所报告的四层石墨烯光谱特征库可用于非侵入性识别特定薄膜中实现的堆叠顺序。
英文摘要：
Tetralayer graphene has recently become a new addition to the family of few-layer graphene with versatile electronic properties. This material can be realised in three distinctive stacking configurations, for which we determine spectroscopic signatures in angle-resolved photoemission spectroscopy (ARPES), dynamical optical conductivity, and Raman spectra of inter-band excitations. The reported library of spectral features of tetralayer graphenes can be used for the non-invasive identification of the stacking order realised in a particular film.
