衬底上石墨烯的弯曲模式

Flexural mode of graphene on a substrate

Bruno Amorim, Francisco Guinea

摘要:

平面外振动在放置在衬底上的石墨烯层中被抑制。悬浮样品中的这些模式与理解诸如电阻率、热膨胀系数等性质有关。我们提出了一个一般的框架,在不同的衬底上的石墨烯的平面外模式的性质的研究。我们使用该模型来估计衬底引起的热膨胀系数的变化,或电阻率的温度依赖性。

英文摘要:

Out of plane vibrations are suppressed in graphene layers placed on a substrate. These modes, in suspended samples, are relevant for the understanding of properties such as the resistivity, the thermal expansion coefficient, and other. We present a general framework for the study of the properties of out of plane modes in graphene on different substrates. We use the model to estimate the substrate induced changes in the thermal expansion coefficient, or in the temperature dependence of the resistivity.
