DESCRIPTION:id=”373″]id=”374″]\n\n제목 : Stacked and twisted 2D materials for tunable optical properties\n\n연사 : 최준호 박사(한국표준과학연구원)\n\nStacked and twisted 2D materials for tunable optical properties\n\nJunho Choi\nNational High Magnetic Field Laboratory, Los Alamos National Laboratory, Los Alamos, New Mexico 87545, USA\n\nVan der Waals (vdW) heterostructures represent a promising material platform with rich electronic and optical properties highly tunable via a wide selection of layer materials, electric doping, strain, and twist angle. Monolayers of transition metal dichalcogenide (TMD) semiconductors commonly show strong light-matter coupling and direct bandgaps from the infrared to the visible spectral range, making them promising candidates for various optoelectronic applications. Vertically stacking different TMD monolayers allows one to create TMD heterostructures with rich and tunable correlated electronic phases and optical properties. Among different methods to tune the properties of vdW heterostructures, the twist angle is the most unique parameter. In this talk, I will discuss how the twist angle controls the temporal and spatial dynamics of interlayer excitons in MoSe2/WSe2 twisted semiconductor bilayers. Also, hybrid vdW heterostructures integrated by 2D semiconductor/ferromagnet will be discussed.\n\n \n\n\n\n \n\nid=”376″]
