ORGANIC MATERIALS PHYSICS LAB
The organic polymer semiconductor material is flexible by maintaining the properties of the polymer, and free deposition is possible on substrates such as glass, plastic, paper, and fiber even at temperatures close to room temperature. Organic electronic devices capable of various physical/chemical changes have scalability in various fields and methods compared to conventional silicon-based devices.
In order to induce self-assembly of polymer organic semiconductor materials at the air-liquid interface, we are making efforts to fabricate atomic-level flat thin films using the Langmuir-Schaefer method. By analyzing the thin film through neutron reflectivity measurement, X-ray reflectivity measurement, AFM, and TEM, and comparing it with the performance of the thin film transistor, we study the structure and performance of the thin film and the proper transistor manufacturing method.
