Course description and aims
This course focuses on organic semiconductor materials as large-area thin film semiconductors for imaging devices. Topics include the electrical properties of organic semiconductors i. e., electric conduction, carrier transport, and photo carrier generation in organic materials. The course enables students to understand how to choice the suitable materials for imaging devices such as xerography, organic light emitting diode, organic transistor, and organic thin film solar cell.
Much information flows in our life, today. In this course, at first, we discuss "What is information?" and imaging process and devices are necessary for human to recognize the information. The large-area thin film semiconductors are required for imaging devices such photoreceptor of laser printer, active matrix display, and organic light emitting diode. Electrical quality of organic materials is worse than that of inorganic materials such as silicon, however, the organic materials have some advantages, in fact, organic semiconductors are used as photoreceptor of xerography.
Student learning outcomes
By the end of this course, students will be able to:
1) Understand the reason why large area thin film semiconductor is required for imaging devices.
2) Understand how to use the nature of organic materials for imaging devices such as xerography.
3) Understand basic properties of organic semiconductors.
4) Understand the relationship of chemical structure of organic semiconductors and characteristics as semiconductors.
Keywords
imaging devices, large area thin film semiconductors, xerography, active matrix, organic semiconductors, hopping transport, transient photocurrent, space charge limited current, disorder model, onsager model, organic light emitting diode, organic transistor, organic thin film solar cells
Competencies that will be developed
| ✔ Specialist skills | Intercultural skills | Communication skills | Critical thinking skills | ✔ Practical and/or problem-solving skills |
Class flow
Towards the end of class, students are given exercise problems related to the lecture given that day to solve. To prepare for class, students should read the course schedule section and check what topics will be covered. Required learning should be completed outside of the classroom for preparation and review purposes.
