Copper ion liquid-like thermoelectrics
Huili Liu,Xun Shi,Fangfang Xu,Linlin Zhang,Wenqing Zhang,Lidong Chen,Qiang Li,Ctirad Uher,Tristan Day,G. Jeffrey Snyder +9 more
TL;DR: The results indicate a new strategy and direction for high-efficiency thermoelectric materials by exploring systems where there exists a crystalline sublattice for electronic conduction surrounded by liquid-like ions.
Journal ArticleDOI
Rationally Designing High-Performance Bulk Thermoelectric Materials
TL;DR: This review describes the recent advances in designing high-performance bulk thermoelectric materials and highlights the decoupling of the electron and phonon transport through coherent interface, matrix/precipitate electronic bands alignment, and compositionally alloyed nanostructures.

Superionics: crystal structures and conduction processes
TL;DR: A review of the state of current knowledge concerning the crystal structures and conduction processes of superionic conductors can be found in this article, where the relative importance of factors such as bonding character and the properties of the mobile and immobile ions in promoting the extensive lattice disorder which characterizes superionic behaviour is assessed and the possibilities for predicting a priori which compounds will display high ionic conductivity discussed.

Design of vanadium oxide structures with controllable electrical properties for energy applications
Changzheng Wu,Feng Feng,Yi Xie +2 more
TL;DR: This review presents an extensive review of the engineering of the microstructures of vanadium oxides with control of their electrical properties, and with attempts to rationally construct energy-related devices, such as aqueous lithium ion batteries, supercapacitors for energy storage, and thermoelectric generators for energy conversion.

On the Sn loss from thin films of the material system Cu-Zn-Sn-S in high vacuum
TL;DR: In this article, a combination of in situ X-ray diffractometry and x-ray fluorescence (XRF) at a synchrotron light source allowed identifying phases, which tend to decompose and evaporate a Sn-containing compound.

Single-crystal neutron-diffraction study of AgI between 23° and 300°C
TL;DR: In this paper, the silver density in the high-temperature α-form consists of a tetrahedrally coordinated equilibrium position ( 1 4 0 1 2 ) and a three-coordinated saddle point (0.39 0.39 ).
