《半导体物理及器件》课程教学知识图谱研究

A Study of the Knowledge Graph for Teaching the Course “Semiconductor Physics and Devices”

摘要: 《半导体物理及器件》是集成电路领域的专业基础课程，其内容涵盖半导体能带论、载流子统计与输运、非平衡载流子，以及pn结、双极型晶体管、MOSFET等关键器件。该课程具有知识点繁多、跨度大等特点，涉及半导体材料的结构、能带、载流子以及多种器件的物理特性，这为教学带来了一定挑战。本文构建了该课程的整体教学知识图谱，清晰展示了核心知识点及其内在逻辑关系，梳理出课程两大部分的关键内容：第一部分“半导体材料属性”中以能带、载流子浓度和双极输运方程为核心，第二部分“半导体器件基础”中以能带图、电流–电压关系和等效电路为重点，并明确了各部分知识点之间的关联。该图谱有助于梳理课程脉络，不仅对本课程的教学具有促进作用，也对集成电路相关课程的推广具有积极意义。

Abstract: Semiconductor Physics and Devices is a fundamental course in the field of integrated circuits. It covers topics such as semiconductor energy band theory, carrier statistics and transport, non-equilibrium carriers, as well as key devices including pn junctions, bipolar junction transistors, and MOSFETs. The course is characterized by its extensive and wide-ranging content, which encompasses the structure, energy bands, and carriers of semiconductor materials, along with the physical properties of various devices, thus presenting certain teaching challenges. This paper presents a comprehensive knowledge graph for teaching this course, which clearly outlines the core concepts and their intrinsic logical relationships. It identifies the key elements of the two main parts of the course: the first part, “Properties of Semiconductor Materials” focuses on energy bands, carrier concentration, and the bipolar transport equations; the second part, “Fundamentals of Semiconductor Devices” emphasizes energy band diagrams, current-voltage relationships, and equivalent circuits, while also clarifying the connections between the knowledge points across sections. This knowledge graph helps in structuring the curriculum coherently, not only facilitating the instruction of this specific course but also promoting the dissemination of integrated circuits-related curricula.
