Welcome to the Yeonjin Yi Research Group in the Department of Physics at Yonsei University! We investigate the electronic structure and electrical properties of soft condensed matter, including organic materials, organic-inorganic hybrid halide perovskites, and hybrid 2D materials.
Functional π-conjugated molecules for application in electronic devices, such as organic light-emitting diodes, organic photovoltaics, organic field-effect transistors
Promising materials for optoelectronics applications, such as light-emitting diodes, solar cells, transistors, and memory devices
Investigating the electronic structure of condensed matter to understand fundamental physics and the mechanisms behind electronic devices.
