Organic Semiconductors
Dr. Heungman Park
Dr. Heungman Park’s research focuses on optoelectronic properties of organic Semiconductors. Organic semiconductors are candidate materials to replace expensive inorganic counterparts such as silicon in optical and optoelectronic applications due to their intrinsically unique material properties. Among organic semiconductors, conjugated polymers have unique materials properties, which are generally flexible and lightweight. It is also relatively easy to control their optoelectronic material properties by reshaping the molecular structure and composition. In addition, many of them are solution-processable so that large area devices can be readily fabricated.
Student Opportunities
Dr. Park’s research group is fabricating and characterizing polymeric organic semiconductor thin films such as PPV-based conjugated polymer films. REU interns will be trained for basic lab skills both of chemical use and lasers, and then they will work on the following experimental projects. 1. Fabricating organic semiconductor thin films and solar cells, 2. Collecting electroluminescence and photoluminescence spectra with respect to sample annealing temperature, nanomaterial dopant concentration and solvents, 3. Learning and participating in data analysis with scientific plotting software and custom-built Python programs.
