Construction of 2D lateral pseudoheterostructures by strain engineering

Journal Article

Abstract


  • Two-dimensional (2D) lateral heterostructures host unconventional physical properties due to

    their controllable band-offset tuning and interfacial sensitive characteristic. The lattice mismatch

    results in the difficulties to construct the perfect atomic interface in such 2D lateral heterostructures,

    which in turn limits their desirable properties and performances in applications. In this work,

    strain-modulated 2D lateral pseudoheterogeneous structures are designed and realized in the singlecomponent

    2D BiOBr nanosheets by taking advantage of their strain-sensitive crystal and electronic

    structures. The pseudoheterogeneous interface without atomic mismatch can be feasibly modulated

    by local strain distribution, which exhibits similar local electronic band structure of corresponding

    heterostructures. Significant enhancement in charge separation at the pseudoheterostructure was

    demonstrated under visible light irradiation, which is given rise to the controllable electronic band

    alignment across the interface. The construction of the lateral pseudoheterostructure offers a feasible

    and promising way to build unprecedented 2D systems with exciting properties.
