posted on 2018-09-25, 11:41 authored by Günther Thiele, Philipp Bron, Sina Lippert, Frederik Nietschke, Oliver Oeckler, Martin Koch, Bernhard Roling, Stefanie DehnenK2Hg2Te3 was synthesized via a mercury-flux synthesis pathway. Single-crystal
and powder X-ray diffraction reveal the compound to be isostructural
to its lighter congener K2Hg2Se3,
yet exhibiting enhanced photoconductivity and electrical conductivity
of (several) orders of magnitude and a decreased thermal conductivity
and band gap. In this report, we elaborate on the synthesis and properties
of the novel ternary compound.
