浅谈“隧道效应与扫描隧道显微镜”的课堂教学

The Classroom Teaching on Tunnel Effect and Scanning Tunnel Microscope

为了让非物理专业大学生能对近代物理以及现代科学知识有所了解,并培养其一定的科学思维和科学方法,本文重点介绍了量子力学中隧道效应的基本理论和扫描隧道显微镜研发制备的科学探索.针对学生数学知识相对薄弱的特点,本文在讲解隧道效应时,着重突出了其物理原理与物理思想,而忽略了相关的数学计算.同时,为了让学生深刻地体会到物理学对现代科学技术发展的影响,引导和激励他们有将科学服务于人类的意识,本文还重点介绍了扫描隧道显微镜在人类认识和改造世界过程中所起到的显著作用.

In order to make non-physics majors understand modern physics and modern scientific knowledge,train their scientific thinking and method,the basic theory of tunnel effect in quantum mechanics and the scientific exploration of the research and development of scanning tunneling microscopy are introduced.To explain the tunnel effect,our paper emphasizes its physical principles and ideas,but neglects the relevant mathematical calculation.In addition,To make students understand the influence of physics on the development of modern science and technology,and then inspire them to have the consciousness of utilizing science to serve Human Beings,our paper also focuses on the significant role of scanning tunneling microscopy in the process of human for understanding and reforming the world.
