Fabrication and Characterization of Organic Thin Film Devices

On the basis of state-of-the-art technologies for organic thin-film transistors and organic solar cells, we are exploring new methods of thin-film fabrication, device patterning, and interface engineering of functional molecular compounds. We have techniques and facilities for the fabrication and characterization of organic electronic devices, including for inkjet patterning of high-performance organic transistors.

2.Inkjet Printing Technique

We are exploring innovative printing techniques for soluble organic functional materials. We have techniques and facilities for the patterning of high-quality crystalline thin films, and for the fabrication and characterization of high-performance organic transistors.

3.Field-Induced Electron Spin Resonance Spectroscopy

We utilize electron spin resonance (ESR) as a microscopic probe of organic field-effect transistors. We observe the gate-induced carriers in the transistors by performing the ESR measurement under the gate voltages.

4.Synthesis of Functional Molecular Materials

We have the techniques and facilities to synthesize and characterize functional molecular compounds and to grow single crystals of these materials.
