Room-temperature epitaxial growth of indium tin oxide thin films on Si substrates with an epitaxial CeO2 ultrathin buffer

Effect of Mn doping on the leakage current and polarization properties in K_0.14Na_0.86NbO₃ ferroelectric single crystals

“…This P r value was larger than those of reported KNN-based ceramics. 88), 99) The crystals annealed at 850°C did not show an apparent hysteresis loop due to their high J. Figure 6 shows the temperature dependence of dielectric permittivity (¾ r ) and loss (tan ¤) measured along [100] cubic at 1 MHz of KNN and Mn-KNN annealed at 1100°C in air.…”

Room-temperature selective epitaxial growth of CoO (1 1 1) and Co3O4 (1 1 1) thin films with atomic steps by pulsed laser deposition

“…In low-temperature epitaxial growth of thin films, crystal nucleation occurs in preference to grain growth, which suppresses island type growth, sintering, and thermal diffusion. This results in not only a flat surface and sharp interface but also the appearance of a quantum size effect that could benefit the development of electronic devices including assembled thin films and nanomaterials [3][4][5]. As a strategy for epitaxial growth, pulsed laser deposition (PLD) involves the ablation of high-energy film precursors from the target onto a substrate at a supersonic speed (∼10 4 m/s); this method is especially useful for nucleation at low temperatures, room temperature in particular.…”

Reverse precipitation synthesis and characterization of CeO2 nanopowder

“…In recent years, nanocrystalline cerium oxide (CeO 2 ) particles have been extensively studied owing to their potential uses in many applications, such as UV absorbents and filters [2], buffer layers with silicon wafer [3], gas sensors [4], catalysts in the fuel cell technology [5], catalytic wet oxidation [6], engine exhaust catalysts [7], NO removal [8], photocatalytic oxidation of water [9], etc. CeO 2 nanopowders have been reported to be synthesized by different techniques such as: hydrothermal [10], mechanochemical [11], sonochemical [12], combustion synthesis [13], sol-gel [14], semi-batch reactor [15], microemulsion [16] and spray-pyrolysis [17].…”
