Why germanium and silicon are considered as best semiconductors?
Vasansrinivasan999
actually diamond should be much better, if fabrication issues can be solved, it is faster and will operate up to 600ºC junction temperature. Silicon is limited to 150ºC junction temperature and Germanium is limited to 50ºC to 60ºC. Germanium was originally used because it was easiest to purify and process. Silicon is the cheapest material now, it comes from sand and there is no shortage of that.

How many valence shell electrons are there in semiconductor atoms?
Silicon, the most widely used semiconductor, has four valence electrons. This places it in between the conductive metals, which have one to three valence electrons, and the non-conductive non-metals which have five to eight valence electrons.
Is it safe to use super glue on silicon?
It's best to use silicone on silicon.
Should you use thread sealer on head bolts for Chevy 350 to prevent water leakage?
They absolutely have to have silicon or some very good thread sealer. You WILL have a leak intoo your oil and ruin a good motor very quickly! RTV black silicon is best directly on the bolt or stud.
What is considered the best conductor silver aluminum glass or silicon?
Silver has a resistance of 1.59x10(-8). Copper has a resistance of 1.72 x 10(-8) Gold has a resistance of 2.44 x 10(-8) Aluminum has a resistance of 2.82 x 10(-8). So the best is Silver then Copper, then Gold, and last Aluminum. (5/07/09)

What is a good slogan for the element germanium?
Germanium's the best way to get your electricity paid, without the pain of the uranium way!
Why is silicon called a semiconductor?
silics meaning what were more generally termed "the flints" or "Hard Rocks" during the Early Modern era where nowadays as we would say "silica" or "silicates"), and was later mistaken by Humphry Davy in 1800 for a compound. In 1811 Gay-Lussac and Thénard probably prepared impure amorphous silicon through the heating of potassium with silicon tetrafluoride. It was first discovered as an element by Berzelius in 1823. In 1824, Berzelius prepared amorphous silicon using approximately the same method as Lussac. Berzelius also purified the product by repeatedly washing it. Because silicon is an important element in semiconductors and high-tech devices, the high-tech region of Silicon Valley, California is named after this element. silicon is so named because they are the compositions including silica content
Why is silicon the best example of a metalloid?
Silicon (Si) is one of seven elements that are known as the metalloids. This is just a fancy term to describe certain elements that don't behave exactly like metals or exactly like non-metals. The generally accepted list of metalloids is silicon, germanium, boron, arsenic, antimony, tellurium and polonium. Silicon can have properties like a metal or a non-metal depending on what other elements it combines with. Glass is a very common silicon compound that has non-metal qualities, while the silicon used in electronics can be made to act very much like a metal.
The best known metalloid on the periodic table is?
B (boron, 5) Si (silicon, 14) Ge (germanium, 32) As (arsenic, 33) Se (Antimony, 51) Te (Tellurium, 52) Po (Polonium, 84) The question if polonium is a metalloid is disputed; many chemists consider polonium as a metal.
What is the best way to chemically digest germanium?
the best way is to eat salad everyday
Is it safe to use super glue on silicon?
It's best to use silicone on silicon.
What is the modern name for eka-silicon?
Ekasilicon is germanium['eka' is Sanskrit language for: 'first' place down under Si)Germanium was isolated in 1886, and provided the best confirmed prediction of Mendeleev's periodic table, which was built up before the discovery of Ge.(Professor Dmitri Mendeleev published the first Periodic Table of the Atomic Elements in 1869).When he proposed his periodic table, he noted some gaps in the table, and predicted that as-of-yet unknown elements existed with properties appropriate to fill those gaps.
What is the mass of germanium?
it may be i think around 700mg or best thing to try physics websites.Sorry i cant help you germanium is very nearly to silver element.
Which material resists electricity the best?
Silicon
What element is the second best conductor of electricity?
Carbon nanotubes or graphene
What is a semimetal like?
Semi-metals are located along the line between the metals and non-metals in the periodic table. Semi-metals (aka) include boron, silicon, germanium, arsenic, antimony, and tellurium. Polonium is often considered a semi-metal too.
