2022학년도 1학기 물리학과 세미나를 안내해 드립니다.
•연사: 유효빈 교수 (서강대 물리학과)
•제목: Operando transmission electron microscopy investigation on domain dynamics in two dimensional ferroelectric materials
•일시: 5월 19일 목요일 오후 4시 30분
•장소: 베어드홀 103호
•초록: Control of interlayer stacking angle in two-dimensional (2-D) van der Waals (vdW) heterostructure enables one to engineer the crystal symmetry to imprint novel functionality. By stacking two layers of transition metal dichalcogenides (TMD) with designed twist angle, one can break the inversion symmetry and thereby develop vertical electric polarization. The direction of the electric polarization can be switched electrically, suggesting that the twisted bilayer TMD can host ferroelectricity. (이하 첨부파일 참조)
