Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms ( IF 1.3 ) Pub Date : 2021-01-15 , DOI: 10.1016/j.nimb.2020.12.002

In this work we present a fully relativistic formulation for the energy loss of an external charged particle interacting with a 2D material. We model this material as a monolayer of atoms represented by harmonic oscillators, with isotropic or anisotropic electronic vibration modes. We develop the model for a wide range of incident energies and considering both parallel and perpendicular trajectories.

应用于2D材料的振荡器模型:相对论带电粒子的能量损失

在这项工作中,我们为与2D材料相互作用的外部带电粒子的能量损耗提出了一种完全相对论的公式。我们将此材料建模为由谐波振荡器代表的原子的单分子层,具有各向同性或各向异性的电子振动模式。我们针对广泛的入射能量并考虑平行和垂直轨迹开发了该模型。
