Advanced Electronic Materials, EarlyView.A novel strategy for achieving high current density in van der Waals (vdW) heterostructure‐based light‐emitting devices (LEDs) is proposed. Based on this concept, an LED utilizing a WS2/WSe2 heterostructure was fabricated, achieving a current density of 9.4 × 104 A/cm2.
