摘要

在现代教育中,将前沿科技融入物理实验教学是一种创新尝试.针对物理实验教学中电场作用微观机制可视化缺失的难题,本研究设计并实践了基于教学型扫描隧道显微镜(STM)的纳米尺度单分子操控实验.通过自研STM系统与电场调控模块,构建了C60分子提取-转运-释放的可控实验案例,并通过(C60)7团簇合成任务显著提升跨学科创新能力.该案例将前沿技术转化为可复现的教学实验,为微观物理现象的可视化教学提供了创新范式.

Abstract

In modern education, it is an innovative attempt to integrate cuttingedge technology into high school laboratory teaching. Addressing the challenge of visualizing the microscopic mechanisms of electric field effects in physics experimental teaching, this study designs and implements a nanoscale singlemolecule manipulation experiment using a teachingfocused scanning tunneling microscope (STM). By utilizing a selfdeveloped STM system with an electric field control module, we establish a controllable experimental framework for the extraction, transport, and release of C60 molecules. The successful synthesis of (C60)7 clusters notably enhances interdisciplinary innovation capabilities. This approach transforms frontier technology into reproducible teaching experiments, providing a pioneering paradigm for the visualized teaching of microscopic physical phenomena.
