Outline of Final Research Achievements

In this research, I aimed to develop a non-distractive optical method to analyze molecular orientation in nanoscale for future device applications. With the sizing-down of electric devices, there has been a strong demand to reveal the orientation of molecules used in film-type devices. Especially in an organic transistors, the mobility of electrons are determined by the parameters therefore it is crucial to determine the angle of the molecular axis. We combined near-field Raman spectroscopy and polarization measurements to achieve the goal.
