Write any two N-type and P-type semiconductors.

1.	Write any two N-type and P-type semiconductors.
Answer» Following are the difference between n-type and p-type semiconductor— n-type semiconductors 1. When pentavalent impurity atoms like As, sb etc. are added in the instrinsic semiconductor, we get n-type semiconductor. 2. The majority carriers in the n-type semi-conductor are electrons and minority carriers are holes. 3. n_e >> n_h p-type semiconductors 1. When trivalent impurity atoms like gallium, indium etc. are added in the intrisic semi conductor, we get p-type semiconductors. 2. The majority carriers in p-type semiconductor are holes and minority carriers are electrons. 3. m_h >> n_e

Answer»

Following are the difference between n-type and p-type semiconductor—

n-type semiconductors

1. When pentavalent impurity atoms like As, sb etc. are added in the instrinsic semiconductor, we get n-type semiconductor.

2. The majority carriers in the n-type semi-conductor are electrons and minority carriers are holes.

3. n_e >> n_h

p-type semiconductors

1. When trivalent impurity atoms like gallium, indium etc. are added in the intrisic semi conductor, we get p-type semiconductors.

2. The majority carriers in p-type semiconductor are holes and minority carriers are electrons.

3. m_h >> n_e
