Abstract: Solution-processing of semiconductors promises a new manufacturing paradigm by enabling ambient, high-throughput and therefore low-cost fabrication of electronic and optoelectronic materials. These materials include conjugated organic molecules, colloidal quantum dot nanocrystals and hybrid inorganic-organic metal halide perovskites, all of which are making tremendous progress in terms of their performance in electronic, optoelectronic and solar energy devices thanks to intensive research worldwide and in the Research Triangle. This presentation will introduce students to these emerging semiconductors, emphasizing the solution deposition of high quality materials and their ink-process-structure-property relationships. Examples will include solution-printed field-effect transistors and solar cells. These examples will be presented through the perspective of multi-probe in situ investigations to help visualize and better grasp the ink casting, drying and thin film formation processes.
Bio: Aram Amassian is associate professor in the materials science and engineering and member of the Carbon Electronics cluster. He joined NC State University in 2018. He was previously faculty in materials science and engineering at the King Abdullah University of Science and Technology (KAUST), where he was a founding faculty member since joining in 2009. Dr. Amassian has co-authored more than 170 publications in peer reviewed journals and has delivered over 100 invited and keynote lectures. He was awarded the Career Development SABIC Chair for his work on solution processed optoelectronic materials. His research is in the area of thin film semiconductors for electronic and energy applications, where he focuses on solution-processing of organic and hybrid organic-inorganic semiconductor films.
