研究室紹介
Professor Chang-Ju Lee's research lab specializes in advanced energy materials and semiconductor devices, with a strong focus on next-generation energy storage systems and optoelectronic sensors. The lab investigates solid-state batteries using novel inorganic solid electrolytes—particularly halide-based electrolytes—to enhance thermal stability and safety in high-nickel cathode materials. In parallel, the lab develops high-performance wide-bandgap semiconductor devices, such as GaN-based UV photodetectors with multi-layer graphene Schottky contacts, for applications in sensing and renewable energy systems. The research also extends to nuclear energy safety, particularly in the probabilistic safety assessment of advanced small modular reactors (SMART).

6All-solid-state batteries (ASSBs) are expected to address the thermal instability of conventional rechargeable batteries, given nonflammable inorganic solid electrolytes (SEs). However, the interaction between sulfide SEs and electrode materials can cause an exothermic reaction accompanied by the formation of explosive decomposition products. Herein, we demonstrate the enhanced thermal stability of a charged cathode material (Li 1– x Ni 0.6 Co 0.2 Mn 0.2 O 2, x ≈ 0.5) with a Li 3 InCl 6 halide S
We demonstrated a metal-semiconductor-metal type GaN UV sensor for the first time by using multi-layer graphene as a Schottky electrode. Multi-layer graphene shows good Schottky electrode characteristic and fabricated UV sensor shows good UV response characteristics. The maximum dark current density and photo-responsive current density were 6.42 × 10 -9 A/cm 2 and 5.57 × 10 -5 A/cm 2 at the 10 V bias, respectively. UV/visible rejection ratios were higher than 10 3 with each applied bias from 1 V
SMART (System-Integrated Modular Advanced Reactor) is under developing by Korea Atomic Energy Research Institute (KAERI) for power generation and seawater desalination. It employs advanced design concepts, therefore it is essential to develop the new Probabilistic Safety Assessment (PSA) validation guidance or add and remove some items in the current PSA review guidance considering the unique characteristics of SMART. In this paper major technical considerations for SMART PSA review are suggeste
