“…These techniques typically use composition-graded thin film materials. 26 Such approaches should also be useful to examine the effect of chemical composition on thermoelectric properties. However, there are also quantities which may depend on the microstructure and directly affect zT, such as thermal diffusivity and carrier mobility.…”

The microstructures and Seebeck coefficients of thermoelectric alloys in the pseudo-ternary PbTeAg 2 Te-Sb 2 Te 3 system were examined using samples that were compositionally graded by unidirectional solidification by the Bridgman method and diffusion couples. At compositions near the middle of the pseudo-binary PbTe-AgSbTe 2 line, a compositionally modulated microstructure has been found. From diffusion couple experiments, it is found that the PbTe-AgSbTe 2 system exhibits a miscibility gap at low temperatures while it forms a complete solid solution at high temperatures; the critical temperature is between 400 C and 450 C. The modulated microstructure originates from the decomposition of the high-temperature solid solution during cooling. Scanning Seebeck coefficient measurement on these samples covers a wide compositional space of the pseudo-ternary system. The Seebeck coefficient transitions from positive values at AgSbTe 2 -rich compositions to negative values at PbTe-rich compositions on the pseudo-binary PbTe-AgSbTe 2 line. Composition-graded samples prepared by the Bridgman method are thus useful to investigate thermoelectric materials in multicomponent systems.

“…There are several outstanding recent reviews on the topic of high-throughput materials science; in particular for the field of catalysis [17]. The interested reader is particularly encouraged to consult recent reviews by Maier et al and Green et al [18,19]. A schematic of the overall high-throughput approach is shown in Fig.…”

The Materials Super Highway: Integrating High-Throughput Experimentation into Mapping the Catalysis Materials Genome

The materials genome initiative (MGI) aims to accelerate the process of materials discovery and reduce the time to commercialization of advanced materials. Thus far, the MGI has resulted in significant progress in computational simulation, modeling, and predictions of catalytic materials. However, prodigious amounts of experimental data are necessary to inform and validate these computational models. High-throughput (HT) methodologies, in which hundreds of materials are rapidly synthesized, processed, and characterized for their figure of merit, represent the key experimental enabler of the theoretical aspects of the MGI. HT methodologies have been used since the early 1980s for identifying novel catalyst formulations and optimizing existing catalysts. Many sophisticated screening and data mining techniques have been developed and since the mid-1990s, this approach has become a widely accepted industrial practice. This article will provide a short history of major developments in HT and will discuss screening approaches combining rapid, qualitative primary screens via thin-film techniques with a series of quantitative screens using plug flow reactors. An illustrative example will be provided of one such study in which novel fuel-flexible sulfur tolerant cracking catalysts were developed. We will then illustrate a path forward that leverages existing HT expertise to validate, provide empirical data to and help guide future theoretical studies.

“…Combinatorial methods have been widely used in pharmaceutical industries for drug discovery [10]. They have been adapted for thin film depositions and attracted a lot of interest in recent years [11][12][13][14][15]. In our combinatorial approach, the lithium niobate deposition is carried out in a high-vacuum chamber in which a novel precursor supply system allows individual spatial control of precursors impinging rates on the substrate.…”

Combinatorial Chemical Vapor Deposition of Lithium Niobate Thin Films

Combinatorial lithium niobate deposition on 150 mm naturally oxidized silicon (100) wafers in a high-vacuum chemical vapor deposition reactor using Li(OBu t ) and Nb(OEt)4(dmae) is presented. The novel precursor supply system allows individual spatial control of precursors impinging rates on the substrate. This results in variations of the film properties in a single experiment at a certain substrate temperature due to the influence of different precursors flow rates and ratios. It efficiently leads to deposition conditions to achieve highly <001> oriented polycrystalline lithium niobate films.
