tellurium

Tellurium has an even greater affinity for gold than arsenic, but tellurium is extremely rare at the surface of the Earth.

Nevertheless, on Earth tellurium has an abundance almost as low as gold, even if tellurium is abundant in the Solar System.

Due to the rarity of tellurium, even if minerals with gold and tellurium are well known they are less frequently found than those were gold is associated with arsenic.

But yes Tellurium is also a nice soft element so AuTl have a good affinity for one another.

A copper sheet coated with a thin layer of lithium-activated tellurium instead of a thicker layer of graphite.

The result of this scarcity of tellurium on Earth is that most of the gold can be found as native gold and only a smaller fraction is found in compounds with tellurium.

Therefore there are many minerals where gold is combined with tellurium (unlike silver and copper, which combine with the smaller sulfur).

Two decades ago, combinations such as lead and tellurium yielded ZT values of around 1.

It is well known that the gold ions have the greatest affinity for the anions of the size of arsenic and tellurium.

Selenium and tellurium are also close of these from this point of view.

Solar energy technologies, for example, will require half the current world supply of tellurium and 25% of the supply of indium, the report says.

Wikipedia: With an abundance in the Earth's crust comparable to that of platinum (about 1 µg/kg), tellurium is one of the rarest stable solid elements.

They don't need a lot of Tellurium, and that's only for the "thin film" cadmium-telluride ones.

Or tellurium in CdTe, supposedly still costeffective compared to “thick” Si cells.

This is Phase Change Memory based on "GST467" or 4 parts Germanium (1.3ppm in the earth's crust), 6 parts Antimony (0.2ppm in the earth's crust), and 7 parts Tellurium (0.001ppm in the earth's crust).

I see your pedantry and I raise you a freshly minted tellurium high pedant coin: it's a bit weird to call the NI border a "real border" given it's completely soft and part of the CTA.

A quick search shows current prices are ~80 $/kg for Tellurium, ~10 $/kg for Antimony, and ~1,300 $/kg for Germanium.

I searched around a little and all I could find is that the thin film type need Tellurium.

Tellurium can play a role in high performance semiconductors.
