Title: Thermoelectrics with a twist

Abstract

Thermoelectrics convert heat into electricity by enabling electron flow across a temperature gradient, but internal electrical resistance from Joule heating is a key limiting factor to conversion efficiency. In the pursuit of material platforms for the next generation of thermoelectrics, topological materials with high electron mobility, including topological insulators and topological semimetals, have attracted substantial attention. Topological insulators support protected current-carrying electron states that are robust to perturbations, reducing electrical resistance.

Enhanced thermoelectric performance of nanostructured topological insulator Bi{sub 2}Se{sub 3}

Journal Article Sun, G. L. ; School of Physics and Materials Science, Anhui University, Hefei 230039 ; Li, L. L. ; ... - Applied Physics Letters

To enhance thermoelectric performance by utilizing topological properties of topological insulators has attracted increasing attention. Here, we show that as grain size decreases from microns to ∼80 nm in thickness, the electron mobility μ increases steeply from 12–15 cm{sup 2} V{sup −1} s{sup −1} to ∼600 cm{sup 2} V{sup −1} s{sup −1}, owing to the contribution of increased topologically protected conducting surfaces. Simultaneously, its lattice thermal conductivity is lowered by ∼30%–50% due to enhanced phonon scattering from the increased grain boundaries. As a result, thermoelectric figure of merit, ZT, of all the fine-grained samples is improved. Specifically, a maximum value of ZT = ∼0.63 is achieved for Bi{sub 2}Se{submore » 3} at T = ∼570 K.« less

Topological Dirac line nodes and superconductivity coexist in SnSe at high pressure

Journal Article Chen, Xuliang ; Lu, Pengchao ; Wang, Xuefei ; ... - Physical Review B

We report on the discovery of a pressure-induced topological and superconducting phase of SnSe, a material which attracts much attention recently due to its superior thermoelectric properties. In situ high-pressure electrical transport and synchrotron x-ray diffraction measurements show that the superconductivity emerges along with the formation of a CsCl-type structural phase of SnSe above around 27 GPa, with a maximum critical temperature of 3.2 K at 39 GPa. Based on ab initio calculations, this CsCl-type SnSe is predicted to be a Dirac line-node (DLN) semimetal in the absence of spin-orbit coupling, whose DLN states are protected by the coexistence ofmore »« less

Prospects of nanostructures Bi{sub 1-x}Sb{sub x} for thermoelectricity

Journal Article Nikolaeva, Albina A., E-mail: A.Nikolaeva@nano.asm.md ; International Laboratory of High Magnetic Fields and Low Temperatures, Wroclaw ; Konopko, Leonid A. ; ... - Journal of Solid State Chemistry

It has been predicted that surface states of topological insulators have large a thermopower and also ultrahigh mobilities. The authors report results of a magneto-thermoelectric investigation of single crystal Bi{sub 1-x}Sb{sub x} nanowires in a glass cover with diameters ranging from 90 nm to 5 {mu}m. The wide-ranging antimony concentration enabled us to study the effect of nanowire dimensionality in the semimetal, semi-conductor and gapless regimes. Quantum size effects in Bi-2 at%Sb nanowires, which are shown in temperature dependences of resistance R(T) and thermopower {alpha}(T) for the diameters significantly higher than the critical diameter for pure Bi-wires, are observed.

Crystallization and Thermoelectric Transport in Semiconductor Micro- and Nanostructures Under Extreme Conditions

Technical Report Gokirmak, Ali ; Silva, Helena

This project focused on thermoelectric transport in semiconductor micro and nanostructures where moderate and typical operating voltages and currents lead to extreme thermal gradients and current densities. Models that describe behavior of semiconducting materials typically assume an equilibrium condition or slight deviations from it. In these cases the generation-recombination processes are assumed to have reached a local equilibrium for a given temperature. Hence, free carrier concentrations and their mobilities, band-gap, thermal conductivity, thermoelectric properties, mobility of atoms and mechanical properties of the material, can be described as a function of temperature. In the case of PN junctions under electrical bias,more »« less

Modular Isotopic Thermoelectric Generator

Technical Report Schock, Alfred

Advanced RTG concepts utilizing improved thermoelectric materials and converter concepts are under study at Fairchild for DOE. The design described here is based on DOE's newly developed radioisotope heat source, and on an improved silicon-germanium material and a multicouple converter module under development at Syncal. Fairchild's assignment was to combine the above into an attractive power system for use in space, and to assess the specific power and other attributes of that design. The resultant design is highly modular, consisting of standard RTG slices, each producing ~24 watts at the desired output voltage of 28 volt. Thus, the design couldmore »« less
