State whether given statement is True or False
A silicon crystal is doped with arsenic impurity
A silicon crystal is doped with arsenic impurity
Open in App
Solution
The correct option is B False
A silicon crystal is a p−type semiconductorp−type semiconductors are doped with trivalent atoms like boron, aluminium etc.But Arsenic impurity is pentavalent, so it is not used to dope with silicon crystal.Therefore the given statement is false.
