Abstract

The relative efficiency of a thermoelectric material is measured in terms of a dimensionless figure of merit, ZT. Though all known thermoelectric materials are believed to have ZT{le}1, recent theoretical results predict that thermoelectric devices fabricated as two-dimensional quantum wells (2D QWs) or one-dimensional (ID) quantum wires could have ZT{ge}3. Multilayers with the dimensions of 2D QWs have been synthesized by alternately sputtering thermoelectric and barrier materials onto a moving single-crystal sapphire substrate from dual magnetrons. These materials have been used to test the thermoelectric quantum well concept and gain insight into relevant transport mechanisms. If successful, research could lead to thermoelectric devices that have efficiencies close to that of an ideal Carnot engine. Ultimately, such devices could be used to replace conventional heat engines and mechanical refrigeration systems.

Synthesis of ceramics from solutions: Functionally graded composites, nanocomposites and single crystal thin films. Technical report No. 1 December 1995-November 1996

Polli, A.D. ; Lange, F.F. ; Levi, C.G.

The crystallization, transformation, and partitioning of amorphous PbO-ZrO2-TiO2 powders produced by pyrolytic decomposition of mixed alkoxide precursors were investigated. Materials have the general formulation Pb1+xTi1/(1+PHI)ZrPHI/(1+PHI)O3+x, where {minus}0.2{le}x{le}0.2 is the fraction PbO excess/deficiency and 0{le}phi{le}1 is the Zr/Ti molar ratio. Most compositions first crystallized as a metastable fluorite structure with varying degrees of pyrochlore-like cation ordering, which transformed to a single perovskite phase upon additional heat treatment. Higher Zr/Ti ratios enhanced the retention of fluorite and reduced the incidence of cation ordering. Compositions with off-stoichiometric amounts of PbO often yielded extended solid solutions prior to partitioning. For example, metastable perovskites withmore »« less
Solid-state dewetting of single- and bilayer Au-W thin films: Unraveling the role of individual layer thickness, stacking sequence and oxidation on morphology evolution

Herz, A., E-mail: andreas.herz@tu-ilmenau.de, E-mail: dong.wang@tu-ilmenau.de ; Franz, A. ; Theska, F. ; ... - AIP Advances

Self-assembly of ultrathin Au, W, and Au-W bilayer thin films is investigated using a rapid thermal annealing technique in an inert ambient. The solid-state dewetting of Au films is briefly revisited in order to emphasize the role of initial film thickness. W films deposited onto SiO{sub 2} evolve into needle-like nanocrystals rather than forming particle-like agglomerates upon annealing at elevated temperatures. Transmission electron microscopy reveals that such nanocrystals actually consist of tungsten (VI) oxide (WO{sub 3}) which is related to an anisotropic oxide crystal growth out of the thin film. The evolution of W films is highly sensitive to themore »« less

Synthesis and evaluation of thermoelectric multilayer films

Wagner, A.V. ; Foreman, R.J. ; Summers, L.J. ; ...

The deposition of compositionally modulated (Bi{sub 1-x}Sb{sub x}){sub 2}(Te{sub 1-y}Se{sub y}){sub 3} thermoelectric multilayer films by magnetron sputtering has been demonstrated. Structures with a period of 140{Angstrom} are shown to be stable to interdiffusion at the high deposition temperatures necessary for growth of single layer crystalline films with ZT {gt} 0.5. These multilayers are of the correct dimension to exhibit the electronic properties of quantum well structures. Furthermore it is shown that the Seebeck coefficient of the films is not degraded by the presence of this multilayer structure. It may be possible to synthesize a multilayer thermoelectric material with enhancedmore »« less

Preparation of superconducting YBa/sub 2/Cu/sub 3/Ox thin films by oxygen annealing of multilayer metal films

Tsaur, B.Y. ; Dilorio, M.S. ; Strauss, A.J.

Superconducting thin films consisting perdominantly of yttrium barium copper oxide have been prepared by oxygen annealing of metal films formed by using electron-beam evaporation to deposit a three-layer sequence of Cu, Ba, and Y in nominally stoichiometric proportions, then repeating the sequence five times. For the best superconducting films, which were prepared on yttria-stabilized cubic zirconia substrates, the onset of superconductivity occurred at 94 K and zero resistivity was observed at 72 K. For the best films prepared on sapphire substrates, the corresponding temperatures were 95 and 40 K.
