摘要： 以微米级2M相WS2单晶为对象，设计了一种多学科交叉的实验教学模式，融合微纳加工、电化学、载流子输运电学和材料科学，旨在通过模拟真实科研场景培养学生的跨学科思维和综合实践能力。实验通过光刻等微纳工艺制备片上微型电极，利用循环伏安法和恒电流充放电法测试WS2锌离子插层/脱嵌的电化学性能，并结合原位光学成像、拉曼光谱和电学测试表征相变机制。本实验不仅引导学生掌握相关理论知识和实验技能，还通过多学科知识整合，激发创新思维，为新能源和信息材料领域高素质人才培养提供实践路径，同时为多学科交叉实验教学设计提供理论与实践参考。

Abstract: This study establishes a multidisciplinary experimental teaching framework centered on micron-scale 2M-phase WS2 single crystals, integrating micro/nanofabrication, electrochemistry, charge transport electronics, and materials science. Designed to simulate authentic research environments, the curriculum cultivates students' interdisciplinary thinking and comprehensive practical skills. The experimental workflow encompasses: (1) on-chip microelectrode fabrication via photolithography and other micro/nanoprocessing techniques, (2) electrochemical evaluation of Zn-ion intercalation/deintercalation in WS2 using cyclic voltammetry and galvanostatic charge-discharge measurements, and (3) mechanistic investigation of phase transitions through synchronized in situ optical imaging, Raman spectroscopy, and electrical characterization. This pedagogical approach not only equips students with fundamental theoretical knowledge and experimental competencies, but also fosters innovative thinking through cross-disciplinary integration. The methodology presents an effective training paradigm for developing high-caliber researchers in emerging energy and information materials fields, while contributing valuable theoretical and practical insights to multidisciplinary experimental education.
