研究室紹介
Professor Jinsub Park's research lab specializes in the design, synthesis, and application of advanced oxide-based nanomaterials for optoelectronic and energy conversion devices. The lab focuses on developing novel ZnO, ZnSnO₃ (ZTO), and Zn₂SnO₄ (c-ZTO) nanostructures and heterostructures with tailored electronic and optical properties, particularly for high-performance UV photodetectors and GaN-based light-emitting diodes (LEDs). Key research directions include nanostructure engineering for enhanced photoresponse speed, light extraction efficiency, and second harmonic generation through periodic polarity inversion. The lab also explores innovative growth techniques such as in situ polarity inversion and transferable microsphere monolayers for device integration.

Selected Papers
15Metal–semiconductor–metal UV photodetectors consisting of transferable zinc-tin-oxide (ZTO) microsphere (MS) monolayers with different phases and sizes are reported. From the experimental results, the crystallized Zn2SnO4 (c-ZTO)-MS-monolayer-based photodetectors present higher performance than amorphous ZnSnO3 (a-ZTO)-based photodetectors. The external quantum efficiencies of the a-ZTO- and c-ZTO-MS-based UV photodetectors are 16.7% (at 320 nm) and 580.9% (at 310 nm), respectively. Moreover, th
