Consider the following statements
(i) An intrinsic semiconductor will behave as insulator at T = 0 K
(ii) Doping pure silicon with trivalent impurities gives p-type semiconductors
(iii) The majority carriers in n-type semiconductors are electrons
(iv) Solar cell works when it is in forward bias
The correct statements(s) is/are
(i) An intrinsic semiconductor will behave as insulator at T = 0 K
(ii) Doping pure silicon with trivalent impurities gives p-type semiconductors
(iii) The majority carriers in n-type semiconductors are electrons
(iv) Solar cell works when it is in forward bias
The correct statements(s) is/are
View answer and explanation
Correct option: C
Only (i), (ii) and (iii)
Option C (Only (i), (ii) and (iii)) is correct because intrinsic semiconductors act as insulators at 0K, doping silicon with trivalent impurities creates p-type semiconductors, and electrons are the majority carriers in n-type semiconductors.
