Research on Innovation Experiment and Practice Teaching Reform of "Semiconductor Physics and Devices"

Abstract

Professional innovation experiment and practice is the key link to broaden students' vision, exercise their thinking, and improve their practical skills in the process of university teaching. It is an important way to increase students' interest in learning, deepen the understanding of esoteric and obscure theoretical knowledge, and catch up with the frontiers of international science. However, due to the limitations of school funding resources, laboratory conditions, and traditional teaching mode, there are many problems during the experimental teaching of "Semiconductor Physics and Devices", such as the insufficient proportion of comprehensive and innovative experiments, outdated experimental contents, and single limited teaching methods that cannot stimulate students' learning interests of students. In response to the abovementioned situation, combined with many years of experience in learning and teaching semiconductor courses and drawing lessons from the advanced teaching modes of international applied technology universities, we creatively adopt the new experimental and practical teaching mode of "in school experiment + out of school practice" and "in-class experiment + extracurricular innovation project expansion". Network interesting experiments and international cutting-edge research topics (such as organic optoelectronic materials) are introduced into our innovative experiments and practical teaching, such as preparing new organic light-emitting pn junction diodes and quantum dot light-emitting diodes, and perovskite thin-film solar cells. Students deeply love these teaching reform measures, stimulate their interest in learning and scientific research, and significantly improve their ability to solve practical problems or scientific research innovation ability, which have achieved preliminary results. The accumulated teaching experience will provide a reference for developing semiconductor physics and devices experimental courses for semiconductor or optoelectronics and microelectronics majors in application-oriented universities.
