Why is silicon a better semiconductor?
Why is silicon preferred over germanium for semiconductors? The reason is that silicon can be processed at a higher temperature compared to germanium. The structure of Germanium crystals will be destroyed at higher temperature. Silicon also has much less leakage current than germanium.
Why do we prefer silicon for transistors?
Silicon is used for electronic devices because it is an element with very special properties. One of its most important properties is that it is a semiconductor. This means that it conducts current under some conditions and acts as an insulator under others.
Why germanium is a semiconductor?
Germanium atoms have one more shell than silicon atoms, but what gives them the interesting semiconductor properties is the fact that both have four electrons in the valence shell. As a consequence, both materials easily form themselves as crystal lattices. Substituted atoms change the electrical properties.
Is germanium a semiconductor or an insulator? Yes, germanium is a semiconductor with four valence electrons. If every atom in a germanium crystal is a germanium atom, the crystal is considered to be an intrinsic semiconductor. A pure semiconductor is an intrinsic semiconductor. Doping is a procedure that increases the conductivity of a semiconductor.
Why silicon and germanium are used as semiconductors?
Silicon and germanium are used effectively here because they have 4 valence electrons in their outermost shell, which allows them to gain or lose electrons equally at the same time.
Why silicon is used as a semiconductor?
A silicon crystal lattice has a diamond cubic crystal structure in a repeating pattern of eight atoms. Each silicon atom is combined with four adjacent silicon atoms with four bonds. Silicon, a very common element, is used as a raw material for semiconductors because of its stable structure.
Why do we use germanium in semiconductors?
In gamma spectroscopy, germanium is preferred because its atomic number is much higher than silicon, which increases the probability of gamma ray interaction. Also, germanium has lower average energy needed to create an electron-hole pair, which is 3.6 eV for silicon and 2.9 eV for germanium.
