Course overview and goals
This course aims to provide students with a systematic understanding of the electronic properties of organic semiconductors and dielectric materials, as well as the operating principles of electronic devices based on these materials. Beginning with fundamental dielectric properties such as polarization and dielectric response, the course covers a broad range of essential concepts in device physics, including molecular orbitals derived from the Hückel method, the HOMO/LUMO framework, charge carrier transport in amorphous and crystalline materials, charge carrier injection from electrodes, and optical absorption and exciton generation.
Building on these fundamentals, the course also examines representative application devices—such as electrophotography, organic light-emitting diodes (OLEDs), organic field-effect transistors (OFETs), and organic photovoltaic cells (OPVs)—with the goal of developing a unified understanding of the relationships between material properties and device performance. By linking key elements including dielectric behavior, electronic states in organic materials, carrier transport, injection interfaces, and photoexcitation processes, students will acquire perspectives necessary for material selection and device design. Upon completion of the course, students are expected to gain advanced and practical knowledge that connects “understanding of material properties” with “understanding of device operation,” enabling them to apply these insights to analysis, design, and problem identification in research on electronic devices.
