telluril

Telluril is a fictional inorganic material described in speculative science and science fiction. It is portrayed as a tellurium-rich compound with distinctive electronic and optical properties that enable advanced devices.

Telluril is depicted as a crystalline solid with a layered or networked lattice. Stoichiometry varies across sources, but common depictions describe tellurium-centered frameworks doped with transition metals such as copper, silver, or platinum. The materials are described as anisotropic with high refractive indices.

In fiction, telluril forms via high-temperature smelting of tellurium-bearing ores, or is synthesized through methods such as chemical vapor deposition, solid-state reaction, or molten-salt electrolysis under controlled conditions.

Telluril is described as a tunable semiconductor with adjustable bandgap and strong nonlinear optical response. It is proposed for photonic circuits, infrared optics, quantum devices, and energy storage components. Some depictions hint at superconductivity at low temperatures, though this remains speculative.

Because telluril is fictional, there is no real-world regulatory status. In-universe discussions treat handling with standard mineral-safety precautions, with fiction-specific hazard notes varying by author.
