Combinatorial pulsed laser deposition and thermoelectricity of (La1−xCax)VO3composition-spread films

“…For the high-throughput evaluation of TE properties of the 10 pieces of film samples simultaneously, we developed such a multi-channel measurement system as shown in Fig. 1(b) [15]. This system enabled us to measure the resistance and Seebeck coefficient of the combinatorial film library compared of ten 1.0 £ 7.5 mm 2 specimens on a substrate.…”

“…A large number of samples (combinatorial library) can be fabricated and evaluated in a single run of experiments. We recently demonstrated the validity of this method for the investigation of ZnO based TE materials [15] among a lot of examples [16].…”

Development of a high-throughput thermoelectric screening tool for combinatorial thin film libraries

“…Although there are a number of literature reports concerning high-throughput characterization tools for composition-spread films [6][7][8], only two address thermoelectric properties. However, these techniques are not applicable for ternary composition-spread films [9,10]. The goal of this paper is to report our recent development of a high-throughput thermoelectric screening tool, and its use to demonstrate mapping of resistance and Seebeck coefficient measurements on a (Ca,Sr,La) 3 Co 4 O 9 ternary composition-spread film.…”

Combinatorial synthesis and high throughput evaluation of thermoelectric power factor in Mg–Si–Ge ternary compounds

“…Recently, several combinatorial approaches were reported in the search for oxide thermoelectric materials [2,3]. The common feature of these approaches is parallel synthesis of an array of small samples with a thin film form.…”

“…One is to scan the heated electrical probes and to evaluate Seebeck coefficient sequentially under temperature difference [2]. The other is to give a temperature difference to entire substrate and to measure properties of thin film samples concurrently through multi-channel probes [3]. We use an integrated ceramic substrate in which local heaters and lead wires are embedded so that one can secure an independent electrical access and local temperature difference to all samples.…”
