Research detail
The organic semiconductor crystal BP1T-CN exhibits polymorphism, showing different single crystals structures. In this study, we have clarified the structural and optical properties of these crystals and evaluated the coherence distribution of BP1T-CN’s electronically excited states in the crystal under optical excitation, by measuring the interference structure of the fluorescence through double slits. This research is still ongoing, but will lead to an evaluation of coherence length variation above and below the lasing threshold, as well as the anisotropy of the coherence distribution along the crystal’s axis.
Comment
I am truly honored to receive this award. I am deeply grateful for the unwavering guidance and support from my supervisors—Katsuki Sensei, Mizuno Sensei, and Garrek Sensei—at the Quantum Photo-Science Laboratory.
