Interfacial charge and energy transfer in van der Waals heterojunctions

InfoMat, 2022
Van der Waals heterojunctions are fast‐emerging quantum structures fabricated by the controlled stacking of two‐dimensional (2D) materials. Owing to the atomically thin thickness, their carrier properties are not only determined by the host material ...

Valley Dependent Optoelectronics from Inversion Symmetry Breaking [PDF]

, 2008
Inversion symmetry breaking allows contrasted circular dichroism in different k-space regions, which takes the extreme form of optical selection rules for interband transitions at high symmetry points.

Rediscovering black phosphorus as an anisotropic layered material for optoelectronics and electronics [PDF]

Nature Communications, 2014
Graphene and transition metal dichalcogenides (TMDCs) are the two major types of layered materials under intensive investigation. However, the zero-bandgap nature of graphene and the relatively low mobility in TMDCs limit their applications.
