We apply the oscillator model to study the energy loss processes of external charged particles interacting with a 2D material characterized by an anisotropic conductivity tensor. We model the material as a monolayer of harmonic oscillators, with anisotropic electronic vibration modes. We focus on the cases of parallel and perpendicular trajectories of the external particle, and we obtain analytical expressions for the stopping power and total energy loss in terms of reduced variables. This allows us to analyze in detail the interaction and to adapt the model to the considered material using adequate values for the physical parameters involved.

使用振荡器模型计算各向异性二维材料中带电粒子的能量损失

我们应用振荡器模型来研究外部带电粒子与具有各向异性电导率张量特征的二维材料相互作用的能量损失过程。我们将该材料建模为具有各向异性电子振动模式的单层谐振子。我们关注外部粒子平行和垂直轨迹的情况，并根据减少的变量获得了阻止本领和总能量损失的解析表达式。这使我们能够详细分析相互作用，并使用所涉及的物理参数的足够值使模型适应所考虑的材料。
