QUID EST VERITAS? (John 18:38)
I was born in Seoul, South Korea, which is the capital city that possesses various cultural diversity. For most of my life, I had grown up along with the city with my parents and sister. I went to Inha University, Incheon, and finished B.S in Chemical Engineering.
Senior year, I decided my mind to become a researcher and started research experience in Semiconductor Nanomaterial Lab (SNL) under the guidance of Prof. Naechul Shin. At that time, I helped set up a new lab by designing a vacuum deposition system.
As a master’s student, I became deeply interested in halide perovskite materials and worked on synthesizing and patterning them via vapor processes. I proposed a bottom-up patterning method based on surface chemistry and suggested several roadmaps to apply halide perovskite thin films for improved stabilization and scalable processing technology. This experience strengthened my desire to pursue further academic research.
Currently, as a Ph.D. candidate in Materials Science and Engineering at the University of California, Irvine, I am focusing on colloidal quantum dot (QD) superlattices and their electronic properties. My work explores how electrospray deposition can minimize spatial disorder in three-dimensional PbSe and PbS QD superlattices, compared to conventional drop-casting. By combining photobase generator ligand exchange and atomic layer deposition infilling, to overcome both spatial and energetic disorders in QD superlattices and probe their miniband transport properties using device platforms such as field-effect transistors and Hall effect measurement.
