Li-Min (Raymond) Chen

Materials Creation Training Program IGERT
University of California, Los Angeles


Li-Min (Raymond) Chen obtained his BS and MS in Materials Science and Engineering from National Cheng Kung University in Taiwan. His previous research focused on the investigation of nanocrystalline zirconium oxide (ZrO2) to replace silicon dioxide (SiO2) as the gate dielectric layer in the metal-oxide-semiconductor (MOS) structure, which is the fundamental component of modern electronic devices. After obtaining his MS, he interned at TSMC, the world’s largest semiconductor manufacturing company, for 5 months. During his internship, he was involved in a company-wide wafer cleaning process modification project for yield improvement, and acquired a thorough understanding of current ULSI manufacturing process. He entered the Materials Science and Engineering Department at UCLA in 2005, and is currently a Ph.D. candidate under the supervision of Prof. Yang Yang. He has been working on electronic devices, such as light-emitting diodes (LED) and solar cells, based on low-cost conjugated polymers, which are novel polymer materials with semiconducting properties. He has been involved in multiple projects, such as the enhancement of polymer LED efficiency by combining fluorescent and phosphorescent dopants and the introduction of additional hole-conducting layers. His current research efforts focus on achieving high performance polymer solar cells through novel structures and materials, such as an inverted structure, a modified anode, low band gap polymers, and hybrid organic-inorganic polymer solar cells. He has recently published an article on the highest-reported power conversion efficiency (PCE) for the inverted structure polymers solar cells. Now he is trying to further increase the device performance through nanoscale engineering.
