    Derek, actually both the Positive and Negative semiconductors are neutralized in charge – nElectrons is equal to nProtons, but however in the Negative Semiconductor, there is an atom called Phosphorus which has 5 electrons and protons so the atoms charge is NOT disrupted, and that 1 extra atop is loosely tied to the phosphorus so it can escape the covalent bond of the semiconductor which will allow current to flow, it is similar with the P type semiconductor

    My gosh I graduated recently as EE and Computer Engineering on MN. What excellent explanations Derek! Getting into the chemistry and providing breadth as well as depth and attempting to anchor the concepts is the pedagogy of a professional lecturer. Thank you for making this so accessible to so many Derek you are close to my heart after spending so many hours with you.

    Somehow I'm having trouble following this, you speed through the information and I can't seem to process it. You know any free resources where I can read about this in more detail?
