Not in JEE Advanced syllabus

An n-type and a p-type silicon semiconductor can be obtained by doping pure silicon with

(A)boron and arsenic respectively
(B)arsenic and boron respectivelyCorrect
(C)sodium and magnesium respectively
(D)indium and sodium respectively

Answer: (B)

Solution

An n-type semiconductor is made by doping a tetravalent element such as silicon with a pentavalent impurity (donor) such as arsenic, phosphorus or antimony, which supplies an extra free electron. A p-type semiconductor is made by doping with a trivalent impurity (acceptor) such as boron, aluminium, gallium or
