      abstract     = {A route to realize strain engineering in weakly bonded
                      heterostructures is presented. Such heterostructures,
                      consisting of layered materials with a pronounced bond
                      hierarchy of strong and weak bonds within and across their
                      building blocks respectively, are anticipated to grow
                      decoupled from each other. Hence, they are expected to be
                      unsuitable for strain engineering as utilized for
                      conventional materials which are strongly bonded
                      isotropically. Here, it is shown for the first time that
                      superlattices of layered chalcogenides (Sb2Te3/GeTe) behave
                      neither as fully decoupled two‐dimensional (2D) materials
                      nor as covalently bonded three‐dimensional (3D) materials.
                      Instead, they form a novel class of 3D solids with an
                      unparalleled atomic arrangement, featuring a distribution of
                      lattice constants, which is tunable. A map to identify
                      further material combinations with similar characteristic is
                      given. It opens the way for the design of a novel class of
                      artificial solids with unexplored properties},
