양자 나노 소자 연구실
Quantum Nano Device Lab
본 연구실에서는 그래핀과 같은 2차원 물질이나 나노튜브와 같은 1차원 물질등 기존의 3차원 물질과는 다른 저차원 물질이 빛과 상호작용하는 물리 현상을 연구하고, 이를 바탕으로 기존에 없던 다양한 반도체 소자, 광학 소자들을 설계하고 구현하고 있습니다. 또한 빛을 나노 구조에 집속시킬 수 있는 플라즈모닉 기술을 원자 수준의 두께를 가진 저차원 물질에 적용하여 광검출기(photodetector), 광발생기(LED), 광조절기(modulator)등을 개발하고 이를 반도체 칩에 집적하여 초고속 통신이나 양자 정보 통신 등에 활용가능한 미래 소자를 개발하고 있습니다.
My main research interest focuses on developing novel optoelectronic devices, such as photodetectors, light emission devices, and optical modulators, using plasmonics and atomically thin low dimensional nanomaterials, including 1-dimensional materials, such as carbon nanotubes, and 2-dimensional materials such as graphene, black phosphorus, and transition metal dichalcogenide (TMDC) sheets. With studying the fundamental physics of quantum materials and optical systems and their hybrid systems, we will utilize those materials/hybrid systems for future optoelectronic applications such as on-chip ultrafast data communication and quantum sensing/communication building blocks.
