Superconducting interaction charge in thallium-based high-Tc cuprates: Roles of cation oxidation state and electronegativity

open access: yes, 2015
Superconductivity in the Tl-based cuprates encompasses a notably broad range of measured optimal transition temperatures Tc0, ranging from lowest in the charge-depleted Tl-1201 compounds (Tl$_{1-x}$(Ba/Sr)$_{1+y}$La$_{1-y}$CuO$_{5-{\delta}}$), such as Tl$
