Visualizing nanoscale charge flows in multi-dimensional WSe2/GaAs vertical diodes (opens in new tab)

The unique properties of transition metal dichalcogenides provide a versatile platform for scalable, room-temperature quantum devices. Their future commercialization will inevitably depend on the development of heterostructures facilitating charge injection into pre-defined areas of 2D components. We showcase here an innovative approach to accurately characterize electrically active nanoscale regions in multidimensional heterostructures made of WSe₂ layers and GaAs, thin films and in-plane on...
