INTRODUCTION We've all heard about . But, do we all know what it is? How it works and what are its uses? To start talking about , we must try to understand the how "normal" conductivity works. This will make it much easier to understand how the ....

... If this balance is disturbed by gain or loss of electrons, the atoms will become electrically charged and are called ions. Electrons occupy energy states. Each level requires a certain amount of energy. For an electron to move to a higher level, it will require the right amount of energy. Electrons can move between different levels and between different materials but to do that, they require the right amount of energy and an "empty" slot in the band they enter. The metallic conductors have a lot of these slots and this is where the free electrons will head when voltage (energy) is applied. A simpler way to look at this is to thi ...
