标题： Optical Properties of Strained Graphene

摘要： 石墨烯单轴拉伸后的光学电导率在Kubo-Greenwood公式框架下进行研究。 关注带间吸收，我们分析并量化了可见光谱区域中普遍透明度的破坏，并解析地描述了透明度随应变和偏振的变化情况。 测量透射率随入射偏振的变化直接反映了应变的大小和方向。 此外，方向依赖的选择规则允许通过监测范霍夫奇点来确定晶格取向。 这些光电弹性效应可以用于探索原子厚度的宽带光学元件。 显示英文摘要

摘要： The optical conductivity of graphene strained uniaxially is studied within the Kubo-Greenwood formalism. Focusing on inter-band absorption, we analyze and quantify the breakdown of universal transparency in the visible region of the spectrum, and analytically characterize the transparency as a function of strain and polarization. Measuring transmittance as a function of incident polarization directly reflects the magnitude and direction of strain. Moreover, direction-dependent selection rules permit identification of the lattice orientation by monitoring the van-Hove transitions. These photoelastic effects in graphene can be explored towards atomically thin, broadband optical elements.
