Germanium Vs. Silicon Wafers

Thin silicon wafers are ubiquitous in the semiconductor business. Provided that there are supplies out there like germanium, why do manufacturers and customers choose to make use of silicon as a substitute? What are its essential advantages over different pure semiconductors like germanium and gallium arsenide?

https://www.metallos.de why silicon is most popular for semiconductors is its abundant provide. Silicon comes from silica sand, which accommodates 95% silicon dioxide. Manufacturers can collect this sand at any quarrying site around the world. Germanium, alternatively, is very scarce. There are solely about 1.5 elements for every million parts in the Earth’s crust.

Due to its plentiful supply, silicon wafers are also cheaper to manufacture en masse than germanium-made ones.

Better Heat Resistance
Another space the place silicon is superior to germanium is heat resistance. Silicon can withstand up to one hundred fifty levels Celsius or roughly 300 levels Fahrenheit. However, germanium wafers are liable to breakage or melting at 70 degrees Celsius or 158 levels Fahrenheit.

Silicon processors are perfect for computers due to their heat resistance. Though it degrades efficiency, these chips can continue to function beyond germanium’s heat tolerance levels with out suffering material damage.

It’s value noting, nevertheless, that germanium had been the material of selection for earlier transistors earlier than silicon overtook it in choice.

Fewer Free Electrons at Room Temperature
Semiconductors’ inherent conductive properties lie between insulators and actual conductors. Doping, or introducing new elements into their atomic construction, enhances these properties so semiconductors can correctly operate when used in electronics.

Doping introduces more electrons that have the potential to turn out to be free and conduct electricity once they receive enough vitality via heat.

At low temperatures, the electrons within the material’s atomic structure don’t possess sufficient energy to break free and orbit the lattice. On this case, the semiconductor functions more like an insulator. However, larger temperatures give some electrons the enhance they want to interrupt the bond and orbit the covalent network of atoms.

Components are solely good conductors if their free electrons are lower than 3. At room temperature, silicon has fewer free electrons than germanium.
