Nanoscale Physics

我的研究计划旨在对纳米结构的物理学有一个基本的了解，纳米结构是尺寸从大约一纳米到几百纳米的系统。纳米结构的性质既不同于单个原子，也不同于宏观的日常物体。它们在从信息处理到医学的各种应用中的重要性得到了广泛的认可。拟议的研究将在这一总主题中有一些重点：我们将在先前成功阐明石墨烯纳米结构的传输特性的基础上再接再厉，包括几纳米宽的碳原子纳米带和一个单原子层厚的纳米带。我们将把这项研究带到一个新的方向，这是因为最近令人惊讶的实验发现，一些长达16微米的石墨烯纳米带在碳化硅衬底上表现出接近

My research program is directed at obtaining a fundamental understanding of the physics of nanostructures, systems with dimensions ranging from about a nanometer to a few hundred nanometers. Nanostructures have properties that differ from those of both individual atoms and macroscopic everyday objects. Their importance for applications ranging from information processing to medicine is widely recognized. The proposed research will have a number of foci within this general theme: We will build on our previous successes elucidating the transport properties of graphene nanostructures, including nanoribbons of carbon atoms several nanometers wide and a single atomic layer thick. We will take this research in a new direction, prompted by the recent surprising experimental discovery that some graphene nanoribbons as long as 16 micrometers on SiC substrates exhibit conductances near
