Tellurium in the Copper Supply Chain
The world copper supply chain can supply tellurium needs for the near term. Without new or bigger U.S. smelters and refineries, Te will be produced elsewhere if sourced from slimes. Domestic Te supply will only increase if more is captured during mineral processing. Losses during slimes processing are not understood which impacts allied production.

Atomic Chains in Nanotubes Push the Electronics Frontier
Atomic chains of tellurium. A bare nanowire is kind of a loose cannon. Controlling its electric behavior — or even just understanding it — is difficult at best when it's in rampant contact with flyaway electrons. Nanowires of tellurium, which is a metalloid similar to selenium and sulfur, is expected to reveal different physical and ...

Here, we report the exfoliation energy of selenium and tellurium atomic chains with non-empirical van der Waals corrections, and their electronic and optical properties with the GW and Bethe-Salpeter formalisms. The exfoliation energy is found to be within 0.547 to 0.719 eV/u.c. for the selenium atomic chain, and 0.737 to 0.926 …
First Solar's growth plans hinge on opaque market for tellurium
First Solar's plan to spend $1.36 billion to help increase module capacity to 16 GW by 2024 seems certain to strain the tellurium market. If the company achieves its goals, its annual demand for the mineral will exceed last year's estimated global production by up to 70%, according to data from a November report by researchers at the Institute ...
