Moiré superlattices in twisted homo-bilayers have revealed unique digital states, together with unconventional superconductivity and correlated insulating phases. Nevertheless, their fabrication course of typically introduces moiré issues, hindering reproducibility and experimental management. Right here, we suggest an alternate method utilizing gradient pressure to assemble moiré superlattices in untwisted bilayer graphene (gs-BLG). By force-field and first-principles calculations, we present that gs-BLG displays kagome-like interlayer-spacing distributions and strain-tunable kagome digital bands. The competitors between interlayer coupling and in-plane pressure rest results in distinct structural deformations, giving rise to a few types of diatomic kagome lattices: delicate, pronounced, and distorted. Kagome digital bands are recognized close to the Fermi degree of their band constructions. Modulating pressure gradients allows tailoring bandwidths and indicators of hopping parameters of those kagome bands, offering a flexible platform for learning unique digital phases. Our findings set up gradient pressure as an alternative choice to twist engineering, opening an avenue for exploring emergent digital phases in graphene-based methods.
