Ferroelectric PbTiO3 nanostructures onto Si-based substrates with size and shape control

Structure, Optical, and Catalytic Properties of Novel Hexagonal Metastable h-MoO3 Nano- and Microrods Synthesized with Modified Liquid-Phase Processes

“…Oxide nanostructures have been extensively explored due to their potential applications in various fields, such as sensors, catalysis, field emission, energy storage and conversion, optoelectronics, magneto-electronics, magneto-optics, and microelectronics, etc. − So far, oxide nanostructures are focused mostly on transition metal oxides, particularly on those with relatively simple ingredients and structures. − Of great interest is molybdenum trioxide because it has different crystalline phases with open structures which make it possible to be applied in different fields. − Molybdenum trioxide is revealed to have several polymorphs: the well-known thermodynamically stable α-MoO 3 (space group Pnma ), metastable β-MoO 3 ( P 2 1 / c ), ε-MoO 3 ( P 2 1 / m ), and hexagonal metastable h -MoO 3 ( P 6 3 / m ) . However, all the polymorphs reported are basically constructed merely in different ways based on the building block of MoO 6 octahedron (see Figure S1, Supporting Information).…”

Hydrothermal synthesis of ferroelectric PbTiO3 nanoparticles with dominant {001} facets by titanate nanostructure

“…At present, contact mode PFM has been widely applied to acquire the hysteresis loops in ferroelectric nanostructures. [24][25][26] Fig. 7a shows a simple sketch map to illustrate the experimental setup for PFM investigations of the PT nanoplates synthesized at 200 uC for 12 h in 7 M NaOH with a Pb/Ti molar ratio of 1.25 : 1.…”

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

“…Lead titanate dots on substrate were derived directly from an uncontinuous thin film [20] or further treated by high temperature annealing [21]. Also, some bottom-up methods, including chemical solution deposition, sol-gel chemistry and microemulsion mediated synthesis [22][23][24], were adopted to prepare nanostructured PT on substrates. Ultrahigh density PT nanodots array on substrate through a microemulsion-assisted chemical solution deposition showed that the nanodots had welldefined epitaxy on the substrate and unique piezoresponse [25], and thus became much closer to real application in ferroelectric devices.…”
