題目:Growth of SiC on Si Substrates and Modification of TiO2 Layers on FTO Substrates
LinkIconinformation

Abstract:
This presentation reports our research that consists of two parts. First, interaction of Si(111) surface with saturated hydrocarbon gases to obtain SiC. Second, modification of TiO2 layers on FTO substrate and its application in dye-sensitized solar cell (DSSC).
Deposition of each CH4 and C2H6 gases on Si(111)-7×7 surface and co-deposition of Si and CH4 gas on Si(111)-7×7 surface at different temperatures are investigated by reflection high-energy electron diffraction (RHEED), quadrupole mass spectroscopy (QMS), scanning electron microscopy (SEM) and atomic force microscopy (AFM). The RHEED patterns during CH4 or C2H6 exposure indicate the evolution of structures such as -7×7, 1×1, 3×3 and SiC at temperatures from RT up to 800oC. Meanwhile, these patterns do not appear in co-deposition of Si and CH4 gas. The amount of CH3 molecules plays a role in structure evolution of Si(111) surfaces. Correlating SEM and AFM images, step modification of Si(111) surfaces will be discussed.
Modification of TiO2 layer on fluorine-doped tin oxide (FTO) substrate has been performed in formation of nanorods and nanofibers. TiO2 nanorods are synthesized through sol-gel method via anodic alumina membrane (AMM) as template. Meanwhile, TiO2 nanofibers are synthesized using electrospinning method. AFM images confirmed that TiO2 nanorods and TiO2 nanofibers have diameter in range 18-30 nm and 100-1000 nm, respectively. TiO2 nanorods and nanofibers layer are applied in DSSC. TiO2 nanorods and nanofibers could increase the DSSC performance compared to use of TiO2 nanoparticles only. It is considered that TiO2 nanorods and nanofibers can be effective in photon trapping thus many photons interact to dyes to produce many excited-electrons.

題目:Novel phase transitions in Fe-based superconductors
LinkIconinformation

Abstract:
It is generally accepted that parent compounds of Fe-based superconductors (FBS) are antiferromagnets with the long-range spin density wave phase (SDW) at temperatures below Néel temperature (TN) (usually ~ 100K). Chemical doping, pressure or strain suppress SDW phase and induce superconductivity. In the first part of the talk, I will discuss our recent study of the multi-band effects in the vicinity of the quantum critical point in P-doped BaFe2As2 thin films.
Usually, FBS have tetragonal crystal structure at high temperatures above the structural transition temperature (Ts), which is quite close to TN in most of cases. However, in some classes Ts and TN differ considerably. In the temperature range Ts < T < TN exotic electronic nematic phase was found. This phase brakes the rotational symmetry of the lattice and results in in-plane anisotropic physical properties. The Ca10(Pt3As8)((Fe1-xPtx)2As2)5 (10-3-8) system is different from this picture. 10-3-8 has a triclinic crystal structure up to room temperature. Therefore, the rotational symmetry of the lattice is broken already at room temperature. We show that this results in a high temperature electronic nematicity. As the temperature decreases, the pseudo gap opens which finally coexists with superconductivity and low temperature SDW phase.
Typically, electronic nematic phase of iron pnictides is magnetic in origin. In this phase the magnetic moments have a preferred orientation in the ab-plane but without long-range magnetic order in contrast to SDW phase. On the other hand, in FeSe it is believed that nematic phase is non-magnetic and electronic nematicity is related to the orbital order. In this talk I will show the muon spin rotation and relaxation (μSR) result of a clean FeSe single crystals with negligibly small amount of Fe excess < 0.1%. The μSR data clearly demonstrate the presence of short-range static magnetism with a very low magnetic moment appeared above the structural transition Ts ~ 90 K. The possible scenarios for the magnetism in FeSe are discussed.

題目:Sub- and Supercritical Fluids for Nano-particles Production
LinkIconinformation

Abstract:
Recently, sub- and supercritical fluids have been applied in wide variety of industrial sectors including food, cosmetics, pharmaceutics, materials, chemistry, energy and waste treatment. Sub- and supercritical fluids may also be utilized for the production of fine powders. Water and carbon dioxide are usually used as a sub- or supercritical fluid solvent, because they are environmentally-friendly benign solvent. Subcritical water was employed to produce macroporous zirconia particles and composite ceria-zirconia particles. The present of ceria in the composite could improve oxygen storage capacity of the particles, while the present of zirconia in the composite could improve thermal resistance of the particles. Therefore, the composite particles may be utilized for electrolyte of Solid Oxide Fuel Cell (SOFC) with high oxygen storage capacity and thermal resistance. Supercritical carbon dioxide was also been applied for production of gold and silver nanoparticles. The modified gold and silver nanoparticles was generated with laser ablation process in supercritical carbon dioxide environment. The gold and silver particles formed were sphere particles attached nanoclusters, which is formed by networking of small sphere particles. The network structure of nanoclusters may modify the properties of nanoparticles. For pharmaceutical application, supercritical carbon dioxide was utilized for fine powder formation of carotenoids (lycopene, β-carotene, and lutein). Supercritical carbon dioxide was employed as anti-solvent of carotenoids dissolved in an organic solvent to generate fine powder. Nano- to submicron particles of carotenoids were produced by this technique without leaving residual organic solvent in the products. These results indicated that supercritical fluids technology may replace the use of organic solvent for material processing.
