2D diamond boron nitride clusters are produced by inducing a sp 2 to sp 3 phase transition with the application of local pressure on atomically thin h‐BN on a SiO 2 substrate, at room temperature, and without chemical functionalization, as demonstrated in article number 2002541 by Elisa Riedo and co‐workers. Molecular dynamics simulations, mechanical measurements, and Raman spectroscopy experiments show a metastable local rearrangement of the h‐BN atoms into diamond crystal clusters, which depends on the applied pressure and number of atomic layers.
