      abstract     = {Ordered arrays of nanocrystals, called supercrystals, have
                      attracted significant attention owing to the collective
                      quantum effects arising from the coupling between
                      neighboring nanocrystals. In particular, lead halide
                      perovskite nanocrystals are widely used because of the
                      combination of the optical properties and faceted cubic
                      shape, which enables the formation of highly ordered
                      supercrystals. The most frequently used method for the
                      fabrication of perovskite supercrystals is based on the
                      self-assembly of nanocrystals from solution via slow
                      evaporation of the solvent. However, the supercrystals
                      produced with this technique grow in random positions on the
                      substrate. Moreover, they are mechanically soft due to the
                      presence of organic ligands around the individual
                      nanocrystals. Therefore, such supercrystals cannot be easily
                      manipulated with microgrippers, which hinders their use in
                      applications. In this work, we synthesize mechanically
                      robust supercrystals built from cubic lead halide perovskite
                      nanocrystals by a two-layer phase diffusion self-assembly
                      with acetonitrile as the antisolvent. This method yields
                      highly faceted thick supercrystals, which are robust enough
                      to be picked up and relocated by microgrippers. We employed
                      X-ray nanodiffraction together with high-resolution scanning
                      electron microscopy and atomic force microscopy to reveal
                      the structure of CsPbBr3, CsPbBr2Cl, and CsPbCl3
                      supercrystals assembled using the two-layer phase diffusion
                      technique and explain their unusual mechanical robustness.
                      Our findings are crucial for further experiments and
                      applications in which supercrystals need to be placed in a
                      precise location, for example, between the electrodes in an
                      electro-optical modulator.},
