semiconductors will be having some charged particles but for practical purpose the free charges should be available in abundant quantity. so in order to increase the charge particles number we add some impurity to these semiconductors . this process is called doping

How are n-type and p-type semiconductors similar?
N-type semiconductor materials which have free electrons,(which are negatively charged).P-type semiconductor materials which have too few electrons. Therefore the opposite of electrons - holes (which are negatively charged).You can think of it like positive and negative poles of a magnet.
Why p type semiconductor is neutral?
becsaus of dopping semiconductor is neuraly filled when n type semiconductor is mixed with p type, majority charge carrier of n type goes to p type and majority of p type goes to n....... this is called as dopping
What are examples of semiconductors?
Germenium and silicon are the examples of Semiconductors.
What extrinsic semiconductor is?
Those semiconductors in which some impurity atoms are embedded are known as extrinsic semiconductors.
What is the difference between power semiconductors and semiconductors?
power semiconductorspower semiconductors can drive large currents during forward biassemiconductorsemiconductors drive small currents during forward bias
Do compound semiconductors behave as intrinsic semiconductors?
Intrinsic refers to the doping -- intrinsic semiconductors are not doped. Whether compound or not, if they are not doped they are intrinsic.
What is doping in extrinisc semiconductors?
3rd and 5th group elements
What are the man-made impurites in semi-conductors called?
doping of semiconductors
What is a degenerate simeconductor Draw an energy band diagram for a degenerate semiconductor?
The semiconductors where the doping concentration becomes equal or larger than the corresponding density of states, then it is referred to as degenerate semiconductors.
What two technologies are used to manufacturer microchips?
Microchips are generally manufactured using photo-lithography to control the placement of semiconductors. The semiconductors are made by doping the metal to alter its electrical properties
Why doping is necessary in PN junction?
In order to fabricate the p type and n type semiconductors..... we are doing the doping process.
What are the examples of p-type semiconductors?
Examples of p-type semiconductors include materials like boron-doped silicon, gallium arsenide, and aluminum gallium arsenide. These materials have a deficiency of electrons, leading to "holes" in the crystal lattice that behave as positive charges.
What is burstein-moss shift?
The shift in the optical band gap of any material, usually semiconductors, due to doping effect is known as Bursteing-Moss shift.
Why semiconductors better than conductors?
Semi-conductor properties can be easily manipulated by doping such as p type and n-type etc can control the electrical properties but not in th case of conductors..
What are the advantage of semiconductor over conductor?
semiconductors are the conducors they are partially conduct electricity. And we can increase therir conductivity by using various method . They are Intrinsic method and extrinsic method . Intrinsic method is heating the semiconducter . Extrinsic method is doping. By using this method the conductivity of semiconductors is rapidly increases. Then we use semiconductors are prefferd to conductors
How are n-type and p-type semiconductors similar?
N-type semiconductor materials which have free electrons,(which are negatively charged).P-type semiconductor materials which have too few electrons. Therefore the opposite of electrons - holes (which are negatively charged).You can think of it like positive and negative poles of a magnet.
What is the effect of doping on depletion region?
increases with doping
