Cation Ordering in Quaternary Sulphides and Selenides
We wish to investigate quaternary chalcogenides, A2ZnBQ4 (where A = Cu, Ag; B = Ge, Sn; Q = S, Se). Calculations indicate stannite (S) or kesterite (K) superstructures of both... -
Structural Changes through the Semiconductor to Metal Transition in Cu2ZnGeSe4
We wish to collect powder neutron diffraction data as a function of temperature to investigate structural changes through a phase transition in the parent thermoelectric phase...
