We investigate structural relaxation in 1D–2D graphene nanoribbon/graphene moiré systems. Unlike 2D patterns, these exhibit distinct phase separation into commensurate and incommensurate regions. This relaxation strongly modulates zigzag edge states, providing a platform for spatially engineering electronic properties.
