    You are spreading the Best Knowledge by books
    Thanks a lot.

    i want 2 know that”does a p-tye semi conductor pocess positive charge?if so why?/if not so why?
    can u please tell me the cler idea with correct explanation.

    • bhavya says:

      a p type semiconductor is definitely not positively charged.
      the “p ” character is due the fact that it is “doped” with an electron deficient impurity which is usually trivalent. Now since Si can form only four bonds at a time, the electron deficient impurity now has a vacant position in its valence shell which provides a vacancy (aka a “hole”) that behaves as an “apparent positive charge” though its merely a vacancy and not a particle.
      hence the semiconductor remains neutral

    • sphoorthi says:

      while doping in a p-type semi conductor holes are created due to less number of electron….due to these holes p-type semi conductor bears a positive charge

      • hitesh says:

        miss sphoorti wether p-type or it is n-type semiconductor, its electrically neutral.
        sure it has available holes in it but the chemistry is neutral..
        oterwise it would be attracting paper pieces like a charged comb do.. hahaha…

    I need books on crystallography ,. It is not available here

    Heat is a form of,when heat is injected into a body then the weight of the body may change or not change.But according to law of conservation energy, energy remains constant its value can not chage but transfer from one form to another form.

    I wanted to know detailed but short note on bcs theory of superconductivity(solid physics).
