One-dimensional (1D) nanostructures coupled with its possible technological applications have fueled the exponential growth of optoelectronics because of the anisotropic transportation of charge-carrier. The geometry confinement provided by 1D nanostructures also alter the optoelectrical characteristic compared to their bulk counterpart. Among of the various fabrication of 1D nanostructure, electrospinning is a versatile assembly method for fabricating uniform and ultrafine nanofibers with different patterning via various geometric collectors. In our lab, we produce diverse functional ES nanofibers and explore their distinctive morphology, opto-electrical properties and applications on organic field-effect transistors (OFETs), light-emitting nanofibers and organic photovoltaics(OPVs).

Organic-inorganic hybrid perovskite materials have emerged as effective photoactive components, which possess exceptional semiconducting properties such as intense light-harvesting capability, small exciton binding energy (~ 20-50 meV), and long charge carrier lifetime (> 100 ns) and diffusion length (> 1 μm). In our team, we utilize the distinctive opto-electrical properties of perovskite to develop novel application of perovskite-related optoelectronics such as photomemory, photonic synapse, resistor-type memory and light-emitting nanofiber.

Non-Volatile Photomemory with Ultrafast and Multi-Level Memory Behavior
Photonic integrated circuits (PICs) that integrate multiple photonic components have shown promising application on data communication system with the features of high speed, large integration capacity and low thermal effects. It is of great urgency to exploration of corresponding photonic components such as light-emitting diodes (LEDs), image sensors, opto-couplers, photodiodes and non-volatile flash photomemory. Among the plethora of derivatives in optical wireless communications, non-volatile flash photomemory is of particular interest since it is the essential building block of computation technology for nowadays big database storage device. In recent years, we have devoted to exploring the mechanisms behind the photo-recording functionality and developing ultrafast responsive photomemory.
