Mixed dimensional van der Waals(VdW)heterostructures constructed by one-dimensional(1D)and two-dimensional(2D)materials exhibit extra degree of freedom to modulate the electronic and optical properties due to the comb...
Light-harvesters with long-lived excited states are desired for efficient solar energy conversion systems. Many solar-to-fuel conversion reactions, such as H2 evolution and CO2 reduction, require multiple sequential e...
