Topographical complexity of micro-clusters. a Illustration of the topographical complexity of the clusters as a result of the boundary shapes, the cleavages, the edge profiles, and the hierarchy. b–e Exemplary SEM images of the inverse pyramidal confinement and three-dimensional clusters formed within the micro-pyramids
