  • Theoretical and Experimental Aspects of Current and Future Research on Nbo2 Thin Film Devices
    crystals Review Theoretical and Experimental Aspects of Current and Future Research on NbO2 Thin Film Devices Denis Music 1,* , Andreas M. Krause 1 and Pär A. T. Olsson 1,2 1 Department of Materials Science and Applied Mathematics, Malmö University, SE-205 06 Malmö, Sweden; [email protected] (A.M.K.); [email protected] (P.A.T.O.) 2 Division of Mechanics, Lund University, Box 118, SE-221 00 Lund, Sweden * Correspondence: [email protected]; Tel.: +46-40-6658709 Abstract: The present research front of NbO2 based memory, energy generation, and storage thin film devices is reviewed. Sputtering plasmas contain NbO, NbO2, and NbO3 clusters, affecting nucleation and growth of NbO2, often leading to a formation of nanorods and nanoslices. NbO2 (I41/a) undergoes the Mott topological transition at 1081 K to rutile (P42/mnm), yielding changes in the electronic structure, which is primarily utilized in memristors. The Seebeck coefficient is a key physical parameter governing the performance of thermoelectric devices, but its temperature behavior is still controversial. Nonetheless, they perform efficiently above 900 K. There is a great potential to improve NbO2 batteries since the theoretical capacity has not been reached, which may be addressed by future diffusion studies. Thermal management of functional materials, comprising thermal stress, thermal fatigue, and thermal shock, is often overlooked even though it can lead to failure. NbO2 exhibits relatively low thermal expansion and high elastic modulus. The future for NbO2 thin film devices looks promising, but there are issues that need to be tackled, such as dependence of properties on strain and grain size, multiple interfaces with point and extended defects, and interaction with various natural and artificial environments, enabling multifunctional Citation: Music, D.; Krause, A.M.; applications and durable performance.

N b ^ and L iN b 03 already have applications in waveguiding devices, such as electro-optic modulators, Fresnel lenses, and SAW transducers. In several cases, however, it would be desirable to grow these oxides on lattice-matched substrates as epitaxial thin films of controlled composition, crystallinity, and thickness: this thesis describes work aimed at achieving this goal.

Booker Assistant Professor of Biochemistry and Molecular Biology Ayusman Sen Professor of Chemistry Head of the Department of Chemistry *Signatures are on file in the Graduate School iii ABSTRACT Alkynyliodonium salts are synthetically useful intermediates that serve as electrophilic acetylene equivalents due to the electron withdrawing nature of the hypervalent iodine. In one example, reaction of an alkynyliodonium salt with soft nucleophiles via conjugate addition, followed by loss of iodobenzene, generates alkylidenecarbenes. Alkylidenecarbenes are divalent, short lived intermediates capable of participating in a various bond-forming processes depending upon the functionality present within the molecule. Due to the wide variety of possible reactions, alkylidenecarbenes are useful reactive intermediates in natural product synthesis. The application of alkynyliodonium salts to generate alkylidenecarbenes is described in the first part of this thesis. Chapter 1 discusses the formation of alkynyliodonium salts and their application towards the generation of alkylidenecarbenes. The total synthesis of radermachol, a natural product target, was examined utilizing an alkylidenecarbene addition to a double bond as a key step.

    pp-03-25-new dots.qxd 10/23/02 2:41 PM Page 611 NICKEL CARBONATE 611 NICKEL CARBONATE [3333-67-3] Formula: NiCO3; MW 118.72 Two basic carbonates are known. They are 2NiCO3•3Ni(OH)2•4H2O [29863- 10-3], and NiCO3•2Ni(OH)2 [12607-70-4], MW 304.17. The second form occurs in nature as a tetrahydrate, mineral, zaratite. Commercial nickel car- bonate is usually the basic salt, 2NiCO3•3Ni(OH)2•4H2O. Uses Nickel carbonate is used to prepare nickel catalysts and several specialty compounds of nickel. It also is used as a neutralizing agent in nickel plating solutions. Other applications are in coloring glass and in the manufacture of ceramic pigments. Physical Properties NiCO3: Light green rhombohedral crystals; decomposes on heating; practi- cally insoluble in water, 93 mg/L at 25°C; dissolves in acids. 2NiCO3•3Ni(OH)2•4H2O: Light green crystals or brown powder; decom- poses on heating; insoluble in water; decomposes in hot water; soluble in acids and in ammonium salts solutions. Zaratite: Emerald greed cubic crystals; density 2.6 g/cm3; insoluble in water; soluble in ammonia and dilute acids. Thermochemical Properties ∆Ηƒ° (NiCO3) –140.6 kcal/mol Preparation Anhydrous nickel carbonate is produced as a precipitate when calcium car- bonate is heated with a solution of nickel chloride in a sealed tube at 150°C. Alternatively, treating nickel powder with ammonia and carbon dioxide fol- lowed by boiling off ammonia yields pure carbonate. When sodium carbonate is added to a solution of Ni(II) salts, basic nickel carbonate precipitates out in impure form.

The structures of the niobium oxide reference materials were checked by selected area electron diffraction to ensure a proper assignment of the fine structures. NbO and Nb2O5 show clearly different energy loss near-edge fine structures of the Nb-M4,5 and -M2,3 edges and of the O-K edge, reflecting the specific local environments of the ionized atoms. To distinguish the two oxides in a quantitative manner, the intensities under the Nb-M4,5 as well as Nb-M2,3 edges and the O-K edge were measured and their ratios calculated. k-factors were also derived from these measurements.
