Germanium, like Silicon, is a semiconductor material.
Germanium was actually more common than Silicon in the early days of semiconductor manufacturing, but it turned out Silicon had a higher tolerance for heat AND was less expensive to make wafers for (silicon is literally dirt-cheap - a large proportion of "dirt" is Silicon, along with Aluminum and Iron).
... the relatively poor heat capacity is going to cause it's OWN issues.

BitFury reports to use immersion cooling on their website to nearly double their efficiency. This would probably give them an advantage to understand the tech well if the next generation is going to run hotter. Seeing those numbers makes me think about researching into it more.
Even when 7nm reaches actual production - what are the YIELDS going to be like?
They are reporting 10 Th/s with 500W on the GMO 7nm chipset, so that's about double the efficiency of an S9 - not a large jump like 28 to 16/14nm - but still significant.
