摘要

以石墨烯为代表的二维材料因电荷和热输运被限制在二维平面内,展现出奇特的物理性质,因而备受关注. 本文将近年来的二维材料物理科学研究发展与教学相融合,开设了“二维材料物理与器件”课程,采用本科生易于理解的语言,结合四大力学基础知识,深入地介绍了二维材料发展历程以及前沿研究进展. 并在教学中加入了机械解离二维材料、二维材料的光谱表征、二维材料场效应管制作、微纳光刻等基础实验,开展了二维物理理论与前沿实验交叉融合的教学尝试,加深了学生对课程内容的理解,建立了正确和深刻的物理图像,并培养了学生的创新能力.

Abstract

Two-dimensional materials such as graphene present novel properties because the charge and heat transport are confined to a two-dimensional plane, which attracts intense research interests. The course teaching and scientific research of two-dimensional materials was integrated in the course of physics and device application of two-dimensional materials. It is introduced that the development of two-dimensional materials especially the recent progress, so that the history and development of two-dimensional materials are clearly introduced, and the overall course is understandable for undergraduates. In addition to the theoretical part, a series of lab experiments are added, such as the exfoliation of two-dimensional materials, Raman spectrum characterization, and fabrication of field effect transistor. By combining the two-dimensional physics theory and in-course experiments, it helps to increase students' perceptual understanding of theoretical knowledge and establishes the correct physical picture.
