本文基于扫描隧道显微镜系统，将相应的前沿学术研究成果引入到实验教学中，详细介绍了如何引导学生完成二维晶体材料C60的制备、结构表征与分析和电子态密度测量.利用前沿物理实验教学的方式，有助于学生深入理解热力学与统计物理和固体物理中晶畴、晶胞以及局域电子态密度等相关概念，提高学生学习理论知识的兴趣，锻炼学生的实践动手能力，促进学生自主学习的内驱力，同时这也符合国家关于教学内容体现创新性、前沿性与时代性的课程建设标准的要求。
Based on the technique of scanning tunneling microscope, this paper introduces the cutting-edge academic research results into experimental physics teaching, and exhibits in detail how to guide students to complete the preparation, structural characterization and analysis of two-dimensional crystal material C60 and the measurement of its electronic density of states. Combined with the experimental teaching method, it can help students deeply understand the related concepts of crystalline domain, unit cell and local electronic density of states in thermodynamics, statistical physics and solid-state physics, improve students interest in theoretical learning, exercise students practical ability and promote students internal interests and motivation of self-directed learning. Consequently, it also meets the requirements of the national curriculum construction standard that the teaching content has to reflect the characteristic of innovation, cutting-edge and modernity.
