Research Interests

My research interest is focusing on organic/inorganic optoelectronic materials and devices, including small molecules, polymers, hybrid perovskites and so on. I’ve mastered the skills of fabrication of multiple type of optoelectronic devices, such as lasers, amplifiers, LEDs, solar cells and FETs, using various solution processing (e. g. spinning coating, inkjet printing) or thermal evaporation methods. I’m also skilled to perform optical/gain property characterization, ultrafast photonics measurements and data analysis on different type of materials in solution or solid state under variable temperature conditions. Besides, I have rich experience in nano imprinting technology for nano structure fabrication (e. g. DFB gratings, waveguide) on different substrates.
