Interfacial Charge-Transfer Dynamics in Type-II Mg1In2Se4/Sb van der Waals Heterostructures for Optoelectronics
Two-dimensional (2D) semiconductors are highly promising for advanced optoelectronics but are fundamentally limited by strong excitonic binding and unbalanced carrier transport. Here, we design a Mg1In2Se4/Sb van der Waals heterostructure that simultaneously overcomes these bottlenecks through synergistic thermodynam...
