What is the use of silicon and germanium?
Silicon-germanium is an important material that is used for the fabrication of SiGe heterojunction bipolar transistors and strained Si metal-oxide-semiconductor (MOS) transistors for advanced complementary metal-oxide-semiconductor (CMOS) and BiCMOS (bipolar CMOS) technologies.
What is difference between n-type and p-type semiconductor?
In N-type semiconductor, electrons are majority carriers and holes are minority carriers. In P-type semiconductor, holes are majority carriers and electrons are minority carriers. It has Larger electron concentration and less hole concentration. It has Larger hole concentration and less electron concentration.
What is semiconductor give example?
A semiconductor material has an electrical conductivity value falling between that of a conductor, such as metallic copper, and an insulator, such as glass. Some examples of semiconductors are silicon, germanium, gallium arsenide, and elements near the so-called “metalloid staircase” on the periodic table.
What is n-type semiconductor?
An n-type semiconductor is an intrinsic semiconductor doped with phosphorus (P), arsenic (As), or antimony (Sb) as an impurity. Silicon of Group IV has four valence electrons and phosphorus of Group V has five valence electrons. * This free electron is the carrier of an n-type semiconductor.
Why is silicon the best semiconductor?
Silicon is used for electronic devices because it is an element with very special properties. One of it’s most important properties is that it is a semiconductor. This means that it conducts electricity under some conditions and acts as an insulator under others. It is even the most common element in the Earth’s crust.
Why is there a silicon shortage?
The world is in the grips of a global chip shortage because of demand for semiconductors surging far beyond capacity for supply. The shortage is crippling players in industries as diverse and far afield as automotives and smartphones—though carmakers have it the worst.
