The cover picture illustrates regularly arrayed quantum‐sized pores and surface nanostructures prepared using an innovative approach of surface patterning. This new approach is based on a well‐controlled pore‐opening process and a modulated anodization process of ultrathin alumina membranes (UTAMs). Using UTAMs with quantum‐sized pores for surface‐patterning processes, ordered arrays of quantum dots are synthesized on silicon substrates. This is the first time in realizing large‐scale regularly arrayed surface structures in the quantum size range using the UTAM technique, which is an important breakthrough in the field of surface nanopatterning. The large‐scale quantum‐dot arrays are promising candidate structures for new types of optoelectronic and display devices on the basis of the quantum‐confinement effect.
