Welcome to Organic Optoelectronic Lab. Organic Optoelectronic Lab is established under Prof. Ben, Bang-Yu Hsu's advice, working on the optoelectronic applications of soft/organic semiconductors. By fine-tuning intermolecular interactions (van der Waals forces) in nanoscale, we can fundamentally control and study the electronic structures of the organic semiconductors evolving from disorder to order. Our goal is to overcome the disorder/low-efficiency organic thin films and achieve ordered morphology that demonstrates high-performance sensing, transporting, emitting in large-scale flexible electronic devices.
