A semiconductor has equal electron and hole concertration `6xx10^(8) m – InterviewSolution

InterviewSolution

1.	A semiconductor has equal electron and hole concertration `6xx10^(8) m^(-3)`. On doping with a certain impurity electron concertration increase to `8xx10^(12) m^(-3)`. Identify the type of semiconductor after doping.
Answer» The resulting semiconductor is n-type as electrons are majority charge carriers in it.
