Organic Electronics

Because organic materials with π electron possess the similar functions as inorganic semiconductors, they have been studied and put into practical use as transistors, solar batteries and electroluminescence devices. These materials are attracting attention for its energy saving qualities and for its applicability to flexible thin-film devices for low-cost printing and coating, which was not possible with the silicon semiconductors that had been commonly used. In this program, students will deepen their understanding of the electronic properties of electronic devices using organic materials, fabricate transistors as practical training, and learn the principles and techniques.

Lectures will be given using books and reference material. Progress will be presented in seminar style followed by a report. Experiments will take place approximately once a week. Status of progress will be reported 2 or 3 times for about one hour. Besides attending assigned practical training, experiments and seminars, there is no obligation.

This course will help students to understand that organic devices, as compared to inorganic semiconductors such as silicon, are easier to handle in simpler facilities, and can be utilized effectively in consideration of environment and energy issues. In particular, student understanding of the characteristics of functional organic material for its mechanical, electrical and optical properties will be deepened. Lectures will be offered on organic electronic devices, including structure, function, and method of handling through experiments.

It is desirable for students to have taken the Soft Device Engineering and Bio-organic Electronic courses that are offered during the first semester in the first year of the doctoral (master degree) program.

The following list shows examples of research projects that can be combined with this course.
"Photoelectric conversion elements and organic electronics "
"Sensor and organic electronics"
"Polymer devices and organic electronics"
