Soft Condensed Matter Physics Lab 

소프트 응집물질물리 연구실

Welcome to the research group led by Yeonjin Yi in the Department of Physics at Yonsei University. Our group is focused on investigating the electronic structure and electrical properties of soft condensed matter, including organic materials, organic-inorganic hybrid halide perovskites, and hybrid 2D materials.

Organic Molecules

Functional π-conjugated molecules for application in electronic devices, such as organic light-emitting didoes, organic photovoltaics, organic field-effect transistor

Organic-Inorganic Hybrid Perovskite

Promising materials  for optoelectronics applications such as light-emitting diodes, solar cells, transistors, and memory devices

Photoelectron Spectroscopy


Exploring the electronic structure of condensed matter to understand fundamental physics and operating mechanisms in electronics
