    Summary: Intercalation of Ag into ZrTe3 produces a “quasi amorphous” intermediate phase until a critical composition of Ag during which the 1D nature is maintained but long range order is otherwise lost as the Zr-Te trigonal prisms transition into octahedra. This is identified by electron diffraction which sporadic peaks all over the place. The introduction of Ag is accompanied by an increase in the superconducting Tc up until Ag composition of 0.5 which falls within the “quasi amorphous” phase. It is hypothesized that the disorder in this phase suppresses CDW and is therefore the cause of increased superconductivity. Personally I would argue that this is NOT in any way amorphous but rather distorted by the fact that the Te atoms are shifting to achieve the phase transformation. But whatever…
