Role of Tellurium Ions for Electrochemically Synthesized Zinc Telluride 2D Structures on Nonconductive Substrate

open access: yesAdvanced Materials Interfaces, 2023
Although electrodeposition has emerged as a promising approach to make metal chalcogenide nanostructures, it has an underlying issue of exfoliating the deposits affixed to a conductive substrate, which is inevitable to transfer electrons for a reduction ...

Metal-non-metal transition in silver chalcogenides

open access: yesPhilosophical Magazine, 1976
Ag2S and Ag2Se undergo polymorphic, first-order transitions at about 133°C and 179°C respectively. Above the transition temperatures both compounds are cubic body centred and characterized by a strongly disturbed sublattice of Ag+ ions in a quasi molten state. This disorder is of course associated with a relatively large ionic conductivity.

Transition-metal substitutions in iron chalcogenides [PDF]

open access: yesPhysical Review B, 2015
The $ab$-plane resistivity and Hall effect are studied in Fe$_{1-y}$M$_y$Te$_{0.65}$Se$_{0.35}$ single crystals doped with two transition metal elements, M = Co or Ni, over a wide doping range, $0 \leq y \leq 0.2$. The superconducting transition temperature, $T_{c}$, reaches zero for Co at $y \simeq 0.14$ and for Ni at $y \simeq 0.032$, while the ...
