TaSe6type

TaSe6type refers to a class of layered inorganic crystalline materials with a specific crystal structure. These compounds generally possess the chemical formula MSe6, where M represents a transition metal, most commonly tantalum (Ta). The defining characteristic of this structure is the presence of chains of selenium atoms running along one crystallographic axis, with the metal atoms located between these chains. This arrangement leads to a one-dimensional (1D) character in their electronic and structural properties, even though they are typically found in a bulk, three-dimensional solid.

The TaSe6type materials are known for their anisotropic properties. Due to the chain-like nature of the selenium atoms, charge transport and other physical phenomena often exhibit strong directional dependence. This anisotropy can lead to interesting electronic and optical behaviors, making them subjects of research in condensed matter physics and materials science. While tantalum selenide compounds are the most prominent examples, similar structural motifs can be found in other transition metal chalcogenides, leading to the broader classification of TaSe6type. Studies often focus on their potential applications in areas such as superconductivity, thermoelectricity, and as components in novel electronic devices, leveraging their unique structural and electronic anisotropy.
