How does the molecular bonding effect the resistivity of a material?

  1. Dec 24, 2011 #1
    Hello all, I want to understand the molecular structure for different electronic components:

    Conductors - need to have metallic bonding, where electrons are free to move about

    Dielectrics - are insulators, but ideally atoms need to be polarizable, without charge actually being able to transfer

    Resistors - ?

    I know that R (ohms) = p*L/A; so what I am really asking is how does the molecular structure effect the p (resistivity) of a material?

    I am guessing that they should be "even more insulating than dielectrics". Meaning that the atoms should not be able to transfer charge or even polarize....can anyone provide any insight on this?

    Thanks :)
