Abstract

The optoelectronic properties of van der Waals heterostructures (vdWHs) made of two-dimensional materials depend on charge and energy transfer across their atomically thin layers. However, these competing processes remain poorly understood. A new experimental study of a model vdWH reveals details of these dynamics that will be essential for future designs of devices based on vdWHs.
