LAB

QUANTUM nano-bio MATERIALS SIMULATION GROUP

Wecome to KAIST's Quantum Materials Simulation Group (QnMSG) led by Prof. Yong-Hyun Kim since 2009, now permanently settled at Department of Physics. We are performing large-scale ab initio electronic structure calculations and molecular dynamics of nano-bio materials using state-of-the-art supercomputers. Currently, we are interested in fundamental sciences of nanostructured energy materials, graphene/carbon nanotube, nano-bio hybrids, nanocluster/protein melting, finite-temperature thermodynamics, friction, and thermoelectricity.

KAIST 양자물성이론 연구실은 2009년부터 김용현 교수가 이끌고 있고 현재 물리학과와 나노학과에 소속되어 있습니다. 실제 물질에서 일어나는 자연현상을 양자역학과 슈퍼컴퓨터를 이용해 설명하고 예측하는 100% 이론 연구실로서 다양한 실험그룹과 공동연구를 수행하고 있습니다. 연구분야는 반도체 물질, 표면/계면, 나노물질, 에너지물질, 마찰, 열전영상 등입니다.
