CellMatch: Combining two unit cells into a common supercell with minimal strain
Description
Abstract Recent emergence of 2D materials (the so-called van der Waals materials), of which graphene is the most famous one, opens new routes in creation of novel materials by mere layer-by-layer combinations. Moreover, a growth of such materials is typically done on a substrate. In both cases structures appear that are periodical in the plane but the periodicity is very different from simple 1 × 1 commensurate unit cells combinations which appears for materials with very similar values of lattice con...
