Title: Comparison of Skutterudites and Advanced Thin-Film B4C/B9C and Si/SiGe Materials in Advanced Thermoelectric Energy Recovery Systems

Abstract

Various advanced thermoelectric (TE) materials have properties that are inherently advantageous for particular TE energy recovery applications. Skutterudites, 0- and 1-dimensional quantum-well materials, and thin-film superlattice materials are providing enhanced opportunities for advanced TE energy recovery. This work demonstrates that early skutterudites materials in dual-material, segmented couple designs may be best suited for higher temperature applications associated with spacecraft power systems and very high temperature exhaust waste heat recovery in heavy vehicles. Early thin-film BxC/Si-SiGe materials appear to be well suited for mid-temperature ranges in exhaust waste heat recovery in heavy-duty and passenger vehicles. Potential power generation at specific exhaust temperature levels and for various heat exchanger performance levels are presented showing the current design sensitivities using each of these TE material sets. Mathematical relationships inherently linking optimum TE design variables and the thermal systems design (i.e., heat exchangers) are also investigated.

  • The figure-of-merit (Z) of a thermoelectric material is defined as Z = S{sup 2}/{rho}k, where S is the Seebeck coefficient, {rho} is the electrical resistivity, and k is the thermal conductivity. Since Z is composed of three components, it is sensitive to measurement errors in each of the components. For example, a Seebeck coefficient measurement which is only 17% high combined with electrical resistivity and thermal conductivity measurements which are 17% too low will result in a Z value which is double the correct value. It is therefore important to observe correct technique when performing measurements of S, {rho}, andmore » k; and to recognize the limitations of the measurements. The purpose of the course is to address some of those issues in order to increase the accuracy of the thermoelectric measurements.« less
  • The Mg{sub 2}Si-based alloys are promising candidates for thermoelectric energy conversion in the middle-high temperature range in order to replace lead compounds. The main advantages of silicide-based thermoelectrics are the nontoxicity and the abundance of their constituent elements in the earth crust. The drawback of such kind of materials is their oxygen sensitivity at high temperature that entails their use under vacuum or inert atmosphere. In order to limit the corrosion phenomena, nanostructured multilayered molybdenum silicide-based materials were deposited via RF magnetron sputtering onto stainless steel, alumina and silicon (100) to set up the deposition process and then onto Mg{submore » 2}Si pellets. XRD, EDS, FE-SEM and electrical measurements at high temperature were carried out in order to obtain, respectively, the structural, compositional, morphological and electrical characterization of the deposited coatings. At the end, the mechanical behavior of the system thin film/Mg{sub 2}Si-substrate as a function of temperature and the barrier properties for oxygen protection after thermal treatment in air at high temperature were qualitatively evaluated by FE-SEM.« less
  • Demonstration of high-performance MOS thin-film transistors (TFTs) on elastically strain-sharing single-crystal Si/SiGe/Si nanomembranes (SiNMs) that are transferred to foreign substrates is reported. The transferable SiNMs are realized by first growing pseudomorphic SiGe and Si layers on silicon-on-insulator (SOI) substrates, and then, selectively removing the buried oxide (BOX) layer from the SOI. Before the release, only the SiGe layer is compressively strained. Upon release, part of the compressive strain in the SiGe layer is transferred to the thin Si layers, and the Si layers, thus, become tensile strained. Both the initial compressive strain state in the SiGe layer and the finalmore » strain sharing state between the SiGe and the Si layers are verified with X-ray diffraction measurements. The TFTs are fabricated employing the conventional high-temperature MOS process on the strain-shared SiNMs that are transferred to an oxidized Si substrate. The transferred strained-sharing SiNMs show outstanding thermal stability and can withstand the high-temperature TFT process on the new host substrate. The strained-channel TFTs fabricated on the new host substrate show high current drive capability and an average electron effective mobility of 270 cm{sup 2}/V ldr s. The results suggest that transferable and thermally stable single-crystal elastically strain- sharing SiNMs can serve as excellent active material for high-speed device application with a simple and scalable transfer method. The demonstration of MOS TFTs on the transferable nanomembranes may create the opportunity for future high-speed Si CMOS heterogeneous integration on any substrate.« less
  • The temperature-dependent thermoelectric and structural properties of n-type filled skutterudites were measured from 300 K to about 650 K. In0.2Co4Sb12, and In0.2Ce0.05Yb0.1Co4Sb12 exhibited ZT values as high as 1.2 at 620 K and In0.2Ce0.15Co4Sb12 showed ZT values of ~1.4 at 675 K. The room temperature Young’s modulus, Poisson’s ratio and coefficient of thermal expansion (CTE at 473 K) of In0.2Ce0.15Co4Sb12, In0.2Co4Sb12, and In0.2Ce0.05Yb0.1Co4Sb12 compositions were found to be lower than that for the unfilled Co4Sb12 skutterudite material. It was discovered that thermal cycling of n-type In0.15Ce0.1Co4Sb12 and In0.2Ce0.17Co4Sb12 materials from 323 K to 673 K (200 cycles) actually increased theirmore » power factors by 14-36% at 510 K to 525 K without appreciably changing the Young’s modulus or the Poisson’s ratio. The transport and structural properties characterized in this work are critical to transitioning these materials into operating TE devices and systems.« less
