Park group’s research interests are classified into Advanced optoelectronics and  Energy harvesting devices using the low dimensional compound semiconductors. Our goal is to replace with classical semiconductor materials by advanced compound semiconductor material system.

Advanced Light-emitting Diodes: Currently we are mainly conducting research related to the light emitting diodes (LEDs) using the nanohybrid structures formed on compound thin-film semiconductors. We have developed the various methods to improve the internal and extraction quantum efficiency of GaN-based LEDs by using the core-shell nanostructures, surface periodic nanostructures, and surface plasmonic. We are very interested in the low dimensional LED such as micro, QD or nanoscale

Metal-oxide Nanospheres Monolayers and Thermal Management: For the application of transferable MO nanospheres monolayer, the flexible hybrid devices(solar cell, perovskite, etc) and electronic devices (FET, Memory, etc) are under investigation. Especially we are very interested in the MO nanomaterial-based monolayer formation and applications to the various electronic and optoelectronic devices. In order to improve the Optical, Electrical and Thermal properties of semiconductor devices, we are trying to use the metal nanowires and metal oxide nanomaterials with control of various surface morphology
