Excitons can be trapped by moiré potentials in van der Waals (vdW) heterostructures, forming ordered arrays of quantum dots. Excitons can also be trapped by defect potentials as single photon emitters ...
(Nanowerk Spotlight) Blackbody response is highly desired in two-dimensional (2D) infrared photodetectors, which determines their practical applications. State-of-the-art available blackbody response ...
