Please do help 0 votes 0 votes khyati commented Jun 28, 2016 reply Follow Share ISRO syllabus is not fixed. But I googled it and found the answer. But , I approach we should study different types of semi-conductor with ie. p and n type with its pros and cons. Then, it will be easier to answer if such questions are asked. 0 votes 0 votes rajatmyname commented Oct 4, 2016 reply Follow Share @Khyatl Shouldn't the answer be (a).N-type semiconductor has excess of electrons than holes and herating up means gaining of energy which means increasing the electrons than holes.Please help to clear my doubt 0 votes 0 votes Divya Krishnan commented Apr 4, 2018 reply Follow Share I'm unable to find any reference.

0 votes 0 votes I think the answer is option D. Here is a reference: https://www.quora.com/What-happens-when-an-n-type-semi-conductor-is-heated-Will-the-number-of-electrons-and-holes-increase-equally Just think logically... when a metal is heated the charge carriers will get excited -> more free electrons -> more holes So overall electrons and holes are increased (minority and majority charges increases). midhunraj answered Jan 7, 2020 midhunraj comment Share Follow See all 0 reply Please log in or register to add a comment.
