Phase-separation-induced self-assembly of controllable PbTiO3 nanodots on Si substrates

► PbTiO3 nanodots on Si substrates have great potentials in memory devices. ► Phase-separation-induced self-assembly synthesis of PbTiO3 nanodots. ► TBOT concentrations could influence size and density of PbTiO3 nanodots. ► PVP concentrations mainly influence the density of nanodots.
