Metal-non-metal transition in silver chalcogenides

Philosophical 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.

Superconductivity in Metal-Rich Chalcogenide Ta₂Se [PDF]

Inorganic Chemistry, 2020
The metal-metal bond in metal-rich chalcogenide is known to exhibit various structures and dominate interesting physical properties. Ta2Se can be obtained by both arc-melting and solid-state pellet methods. Ta2Se crystallizes a layered tetragonal structure with space group P4/nmm (S.G.129, Pearson symbol tP6).

Mechanism for resistive switching in chalcogenide-based electrochemical metallization memory cells

AIP Advances, 2015
It has been reported that in chalcogenide-based electrochemical metallization (ECM) memory cells (e.g., As2S3:Ag, GeS:Cu, and Ag2S), the metal filament grows from the cathode (e.g., Pt and W) towards the anode (e.g., Cu and Ag), whereas filament growth ...

Symmetry progression and possible polar metallicity in NiPS3 under pressure

npj 2D Materials and Applications, 2022
van der Waals solids are ideal platforms for the discovery of new states of matter and emergent properties under external stimuli. Under pressure, complex chalcogenides like MPS3 (M = Mn, Ni, Co, V) host sliding and structural transitions, insulator-to ...

Strong electron correlations in the normal state of FeSe0.42Te0.58 [PDF]

, 2010
We investigate the normal state of the '11' iron-based superconductor FeSe0.42Te0.58 by angle resolved photoemission. Our data reveal a highly renormalized quasiparticle dispersion characteristic of a strongly correlated metal.

First-Principle Wannier function analysis of the electronic structure of PdTe: Weaker magnetism and superconductivity [PDF]

, 2013
We report a first-principles Wannier function study of the electronic structure of PdTe. Its electronic structure is found to be a broad three-dimensional Fermi surface with highly reduced correlations effects.

Transition-metal substitutions in iron chalcogenides [PDF]

Physical 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 ...
