I Semiconductor is the combination of elements in the groups IV and VI?

  1. Feb 27, 2017 #1
    From my understanding of semiconductors, we are able to create semiconductors by combining different group of elements that fulfill the octet rule to produce covalent bonds and where their electronegativities provide a energy band gap that is between that of a conductor and insulator. Why is the combination of elements in the groups IV-VI a semiconductor? Isn't the octet rule violated?

    the semiconductor does not need to be a binary like a III-V, or a II-VI, you can have other compounds, I worked in chalcopyrites which are III-IV-VI(2)

    What do you have in mind? PbS?
