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.

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 do you obtain n type semiconductors?
by adding pentavalent impurity in d pure semiconducters (like intrinsic semiconducters) is called n type semiconducters
What class elements are semiconductors?
Metalloids
Semiconductors are also called?
Solid state devices.
Why N Type Semiconductors are preferred over P Type Semiconductors?
since n type semiconductors have high mobility for electrons, they are preffered over ptype
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.
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)
What are the applications of electronegativity?
hai To measure the type of bonding in semiconductors
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 n type are electrically neutral?
Why n and p type semiconductors are electrically neutral
What are the semiconductors in the periodic table?
Semiconductors can either be intrinsic or extrinsic. Intrinsic semiconductors are elements that are in their pure form. These will usually have positive and negative sides because the electrons migrate towards one direction. On the other hand, extrinsic semiconductors are when the conductivity (or ability to make an electric charge with the electrons) are controlled by adding other atoms. These atoms that are added are called dopants. Dopants donate or receive electrons from the semiconductor to make impure.
How many semiconductors are present in periodic table?
2
Why minority carriers in P-type is electrons?
The P-type semiconductors have a very large percentage of holes.
Pentavalent elements are added to intrinsic semiconductors elements to produce what type?
N
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.
What is the term for a semiconductors that contains electrons?
N-type semiconductor contains extra electrons.
