• Iino laboratory

    Iino Laboratory belongs to Imaging Science and Engineering Research Center, Laboratory for Future Interdisciplinary Research of Science and Technology (FIRST), Institute of Innovative Research (IIR), Tokyo Institute of Technology, and conducts research on large-area thin film semiconductors used in imaging devices.
    As thin film semiconductors, we are focusing on organic semiconductors that can be formed by a simple coating process, and especally, we are studying "liquid crystalline organic semiconductors" in which molecules aggregate and aligned on substrates in a self-organized manner. The self-organized aggregation of organic semiconductor molecules, even during high-speed film formation, results in an organic semiconductor material with both high process compatibility and high quality electrical properties, which is not possible with conventional organic semiconductors.
    This organic semiconductor material is expected to be applied to imaging devices such as displays because it can be used in the printing process to produce large-area semiconductor thin films with ultra-low energy consumption. In addition, since the film formation process temperature is lower than 100 °C, semiconductor thin films can be formed on inexpensive plastic substrates such as PET, which is expected to be applied to flexible devices.
    In our laboratory, researchers with different backgrounds, such as electrical, chemical, and physical scientists, work together to develop materials, evaluate basic properties, and apply them to devices.
    Most of the students in our laboratory belong to the Electrical and Electronic Engineering Course in the Department of Electrical and Electronic Engineering at the School of Engineering, and many of them have backgrounds in electrical engineering and physics/applied physics, but our research is also an area in which researchers in chemistry/applied chemistry and organic materials can play an active role.
