    PN junctions, which are crucial to the functioning of electronic devices, develop when n-type and p-type semiconductors join. Main difference between n type and p type semiconductors , the following chart is provided.

    • P Type:-

     Group III element is added as a doping element.

     Impurity added creates vacancy of electrons (holes) known as Acceptor Atoms.

     Majority carriers move from higher to lower potential.

     Holes are majority carriers

     Electrons are minority carriers

    • N Type:-

     Group V element is added as a doping element.

     Impurity added provides extra electrons and is called a Donor Atom.

     Majority carriers move from lower to higher potential

     Electrons are majority carriers

     Holes are minority carriers

    The difference between p type and n type are mention below : 

    P-type semiconductor The p-type semiconductor in which  positively charged holes is majority charge carriers are  called P-type semiconductor. 

    i) Here negatively charged electrons Here positively charged holes are are in minority. 

    ii In such type trivalent element In such type pentavalent element such as Boron, Indium or trivalent such as Arsenic or aluminum are element are doped into the pure doped into the pure silicon or silicon or germanium 

    iii) It is formed due to leaving a  vacant space by losing electron from the atoms. 

    N-Type semiconductor The n-type semiconductor in which negatively charged electrons are majority charge and acts as charge is called n type semiconductor. 

    i)Here positively charge holes are minority. 

    ii) in such type pentavalent element such as arsenic or aluminum are doped into the pure silicon or germanium 

    iii) it is formed due to free electron left after forming covalent bond with neighbouring atom.
