A structural differentiation of quaternary copper argyrodites: Structure — property relations of high temperature ion conductors

Abstract

The crystal structures of 12 argyrodite type copper compounds with the general formula CuThis classification corresponds to the physical properties of the argyrodites, especially to their ionic conductivities, which show a significant dependence on the composition.

Optical and electrical properties of Cu6PS5I-based thin films versus copper content variation

“…Due to the presence of vacancies in copper cation sublattice, it is characterized by intrinsic structural disordering [1,2]. Owing to its high ionic conductivity, Cu 6 PS 5 I represents a promising material for renewable energy sources and electrochemical or optical sensors.…”

Electrical and optical parameters of Cu6PS5I-based thin films deposited using magnetron sputtering

“…Cu 6 PS 5 I superionic conductors belong to the argyrodite family, and are characterized by high ionic conductivity, and due to this they are prospective materials for creating renewable energy sources, electrochemical and optical sensors [1][2][3][4]. At room temperature, they belong to the cubic syngony m F 3 4 .…”

Influence of cation substitution on phase transition and optical absorption edge in Cu6(P1-xAsx)S5I mixed crystals

“…Cu 6 PS 5 I and Cu 6 AsS 5 I crystals belong to compounds of the argyrodite structure [1][2][3]. It is well-known that argyrodite crystals are characterized by high ionic conductivity that determines the possibilities of their application in new devices for solid state ionics [4].…”

“…It is well-known that argyrodite crystals are characterized by high ionic conductivity that determines the possibilities of their application in new devices for solid state ionics [4]. The main reasons and peculiarities of high ionic conductivity in materials of this type are studied in the works [1][2][3]. The Cu 6 PS 5 I crystal is the most intensely studied one among argyrodite-type superionic conductors.…”
