The strain applied to transition metal dichalcogenides (TMDs) reduces their energy bandgap, and local strains result in a funnel‐like band structure in which funneled excitons move toward the most strained region. Herein, a funnel device based on asymmetrically strained WS2 and MoS2 is reported. Asymmetric strains are induced by transferring the TMD flakes onto a fork‐shaped SU‐8 microstructure. Raman...
