摘要

Strain engineering of 2D heterostructures is pivotal for next-generation flexible electronics. Here, we investigate the straintronic and spintronic properties of MnO₂/SiC van der Waals heterostructures (vdWHs) using density functional theory (DFT). Our results reveal: (i) a strain-induced transition from Type-I to Type-II band alignment, (ii) emergence of topological signatures under tensile strain, and (iii) enhanced visible-light absorption. The MnO₂/SiC vdWH, with its intrinsic ferromagnetism (4.85 µB) and strain-tunable multitronic responses, offers a unique platform for spintronic and optoelectronic applications unattainable in conventional TMD-based systems.
