石墨烯物理学

Graphene Physics in Graphite

Yakov Kopelevich, Pablo Esquinazi

摘要:

单层碳被称为“石墨烯”,石墨是由它制成的,由于最近令人兴奋的实验结果,它引起了科学界的广泛兴趣。石墨烯从基础研究的角度以及潜在的技术应用来看都很有趣。在这里,我们简要概述了这一领域的最新发展,特别是石墨的电子特性。实验证据表明,高质量的石墨是具有几乎解耦的2D石墨烯平面的多层系统。根据实验观察,我们预计薄石墨样品而不是单层将是石墨烯电子产品最有前途的候选者。

英文摘要:

Single layers of carbon dubbed "graphenes", from which graphite is built, have attracted broad interest in the scientific community because of recent exciting experimental results. Graphene is interesting from a fundamental research perspective, as well as for potential technological applications. Here, we provide a brief overview of recent developments in this field, focusing especially on the electronic properties of graphite. Experimental evidence indicates that high-quality graphite is a multi-layer system with nearly decoupled 2D graphene planes. Based on experimental observations, we anticipate that thin graphite samples and not single layers will be the most promising candidates for graphene-based electronics.
