이번 학기 콜로퀴움은 코로나19 오미크론 변이 급속 확산 및 정부 지침에 따라 온-오프 하이브리드(오프라인+Real Time Streaming)으로 운영될 예정입니다.

네번째 강연에는 홍익대학교의 박상연 교수님을 모시고 콜로퀴움을 개최하오니, 학과 구성원 여러분의 많은 참여를 부탁 드립니다.

코로나19 확산방지를 위해 다과는 제공하지 않습니다.

 5. Abstract: van der Waals (vdW) semiconducting materials, especially monolayered transition metal dichalcogenides (TMDCs, e.g. MoS2, WS2, etc.), have garnered intense interests due to their 2D structure that enables super flexibility, optical transparency, and facile integration with disparate materials through vdW forces. Furthermore, they show excellent electrical and photo‐electrical properties even when they are thinned down to a monolayer, which lead to enormous possibilities in the creation of a wide range of ultrathin, flexible, and transparent optoelectronic devices with new and unique functionalities. This presentation will give an overview of the recent advances in the synthesis of 2D semiconducting materials and their various electronic, optoelectronic, and energy-related applications. This will include the unique thermodynamically stable synthesis method, design of heterostructures, metal-2D contact, strain engineering, and hydrogen evolution using 2D semiconductor.
