研究室紹介
Professor Ji-Eun Kim's research lab specializes in advanced materials characterization and design, with a focus on understanding the complex interplay between chemical and structural heterogeneity and macroscopic material properties. The lab employs cutting-edge techniques such as multislice electron ptychography and bond valence molecular dynamics simulations to probe atomic-scale phenomena in functional oxides, particularly relaxor ferroelectrics. Their work reveals how strain and local chemical environments jointly influence polar nanoregions and dielectric behavior, enabling the rational design of next-generation electronic and energy materials. The lab bridges experimental microscopy with predictive modeling to address challenges in materials performance and reliability.

2The focus of this study is to investigate the assignment of weapons to multiple targets in a scenario, specifically when an air defense system is confronted with numerous targets, such as low-altitude rockets or groups of drones. The accuracy of weapons in destroying these targets depends heavily on the correct alignment of the launchers with the targets, which can be affected by errors in launcher orientation. Therefore, in solving weapon–target assignment (WTA) problems, it is crucial to accou
Introducing structural and/or chemical heterogeneity into otherwise ordered crystals can dramatically alter material properties. Lead-based relaxor ferroelectrics, such as 0.68Pb(Mg1/3Nb2/3)O3-0.32PbTiO3, are prototypical examples. Here, we perform three-dimensional volumetric characterization using multislice electron ptychography (MEP) and bond valence molecular dynamics (BVMD) simulations. Real-space comparisons between the two under varying strain states reveal a coherent three-dimensional v
