We’ve now explored why you should decide on germanium around sapphire but why would you pick germanium more than silicon or vice versa?
Ge is additionally great electromagnetic interference (EMI) shielding substance. Its Unique quality called EMI for its ability to defend versus electromagnetic interference is becoming ever more critical for modern military apps exactly where other alerts (in millimeter and centimeter range) is usually strong plenty of to create nearby IR programs ineffective.
One more thing to consider is germanium’s density. At five.33g/cm3 it doesn't float like a butterfly and sting just like a bee. It’s major. Pretty hefty and this may must be deemed when building weight-sensitive techniques.
