Ironically equipment for the thin film deposition of Germanium specifically the compound Silicon Germanium (SiGe) was export controlled by both Netherlands and Japan, looks like SiGe is necessary for stacking transistors like GAAFET.

I heard Betelgeuse is going supernova soon, if true then bad timing by China
But will take like 640 years for the Germanium to reach the earth.
There's a chance the supernova already happened 639 years and 364 days ago
Nah, we would had already some compelling evidence that exploded, that last phase of a star last like from hundred of thousands of years to millions of years before exploding with the star doing weird things like Betelgeuse, 640 years is just a day in the life on a star.There's a chance the supernova already happened 639 years and 364 days ago
Ahh, forget about the Germanium, the only thing that will reach the earth in 640 years is the photons and the high energy particles of the explosion, the ejecta material (including the germanium) it move at only 0.10c and will probably reach only 4-10 ly from the star to form a space cloud.
Just mine asteroids.

Gallium is mainly obtained as a by-product of aluminum production. This is a particularly energy-intensive process, which is why countries such as China with low electricity costs and very liberal environmental standards enjoy an unbeatable advantage here. Almost 95 percent of the global gallium supply comes from China.
But as with the rare earths, China dominates here mainly because of its cost advantage. If supplies from China were cut off, gallium production in other countries would quickly pay off again.
