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

∙ 10y agoSi and Ge are both group IV elements. This means they have 4 valence electrons in their outer shell. Thus, they can give or accept electrons equally well, allowing them to be doped as N- or P- type easily.

∙ 9y agoSilicon and germanium are used in semiconductor devices because they are elemental semiconductors. There are also binary semiconductors (semiconductors composed of two or more elements) that are used in semiconductor devices, some of which are:
- gallium arsenide
- boron nitride
- gallium aluminum indium phosphide
- indium nitride phosphide
- indium antimonide
- silicon carbide
- copper oxide
- lead sulfide (galena)
- cadmium selenide
- etc.
Pure carbon in the form of diamond or nanotubes should also be an excellent elemental semiconductor, but the fabrication problems have yet to be resolved before it can be used in semiconductor devices. It has been demonstrated in lab prototype devices already.

Because both has valency 4 and show the properties of metals and non-metals.

Why carbon is not used as semiconductor material?
carbon is not used as the semiconductor because it has larger band gap than silicon and germenium
What is an element that is neither a good conductor or a good insulator?
silicon, which is a semiconductor.
What is the narrow-band semiconductor?
Narrow-band semiconductor refers to the semiconductor materials with band gap that is relatively smaller than silicon. This is commonly used as thermo-electric or infrared detectors.
Why germanium semiconductor is used in hall effect experiment not silicon?
germanium low sensitivity
What is the name of two energy bands at which current is produced in silicon?
The two energy bands in which current is produced in Silicon (type of intrinsic semiconductor) are VALENCE BAND & CONDUCTION BAND
What is the most familiar semiconductor?
silicon and germanium
Silicon atoms combine into an orderly pattern What is it called?
semiconductor
Is silicon a extrinsic or intrinsic semiconductor?
silicon is intrinsic semiconductor until we add some impurities in it. the impurities are either of group 3 called acceptors which make p type or of group 5 called donors which make n type semiconductor.
Is silicon a conducter?
Silicon is a semiconductor
Why silicon and germanium called as semiconductor?
Because they have four valence electrons.
Is silicon a semiconductor?
Yes,silicon and germanium are semiconductors.
Is pure silicon an insulator?
Pure silicon is a semiconductor.
Is silicon semiconductor?
Yes
What semiconductor material is used to make transistors?
* silicon * germanium * gallium arsenide * etc.
What semiconductor is used in calculators?
Silicon based semiconductors are the most commonly used semiconductor material in calculators. Silicon semiconductors are also extensively used in computers.
What semiconductor is used in computers?
Silicon.
What do scientists classify silicon as?
a semiconductor
