Why conductivity of n-type semiconductors is greater than p-type semiconductors?
because in n-type there is a real movement of a free negative charge(electrones not positive holes)
How are N type semiconductors formed?
N-type semiconductors are a type of extrinsic semiconductor where the dopant atoms (donors) are capable of providing extra conduction electrons to the host material (e.g. phosphorusin silicon). This creates an excess of negative (n-type) electron charge carriers.
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 is type 1 and type 2 semiconductors?
Type 1 Semiconductors: The bandgap of one semiconductor is completely contained in the bandgap of the other one. In double heterostructure design carriers will be confined in the smaller bandgap material. this structure is used to form barrier/quantum well in Multi quantum well lasers and LEds Type II: like Type I The bandgap of the two materials overlap but the changes in the conduction and valence bands change sign. this type of materials do not use for light emiiting application as carriers can not be confined.
What is the net charge on n type n p type?
n-type and p type has net no charge because the number of proton and electron remain same in a crystal. (shahbaz)
Why N Type Semiconductors are preferred over P Type Semiconductors?
since n type semiconductors have high mobility for electrons, they are preffered over ptype
Why n type are electrically neutral?
Why n and p type semiconductors are electrically neutral
Why conductivity of n-type semiconductors is greater than p-type semiconductors?
because in n-type there is a real movement of a free negative charge(electrones not positive holes)
How are N type semiconductors formed?
N-type semiconductors are a type of extrinsic semiconductor where the dopant atoms (donors) are capable of providing extra conduction electrons to the host material (e.g. phosphorusin silicon). This creates an excess of negative (n-type) electron charge carriers.
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 difference between p-type and n-type semiconductor?
a pure semiconductors with a valency of three doped with a trivalent element is called p-type and a pure semiconductors with a valency of three doped with a pentavalent element is called n-type
What are p type semiconductors?
P type semiconductors have been doped with trivalent elements, causing them to conduct via "hole" flow. N type semiconductors have been doped with pentavalent elements, causing them to conduct via electron flow.
Pentavalent elements are added to intrinsic semiconductors elements to produce what type?
N
What is the term for a semiconductors that contains electrons?
N-type semiconductor contains extra electrons.
What is the term for semiconductors that contains extra electrons?
N-type semiconductor contains extra electrons.
What is an explanation of n-type and p-type semiconductors?
In n-type semiconductor, electricity is conducted by NEGATIVE charges (electrons). In a p-type semiconductor, electricity is conducted by POSITIVE charges (holes).
What element is often used as semiconductors for computer?
Semiconductors are 90% of the time made of Silicon, enhanced into P-Type or N-Type depending on needed polarities. P = Positive, N = Negative, Boron gas has excess negative electrons and is used in doping to create N-Type Silicon.
