Outline of Final Research Achievements

New method and equipments to analyze defects in organic materials or organic semiconductors utilizing terahertz laser spectrometer was developed. I also have succeeded to develop high power and small size terahertz light source, which can be included inside the device manufacturing process equipments like as PVD (Physical Vapor Deposition) chamber.
Molecular vibrations of organic materials were successfully assigned by using THz laser spectroscopy applied to single crystals grown by the originally developed apparatus. Monochromatic THz imaging could reveal crystal form transition as an example of actual real time monitoring.
