Band Gap and Semiconductor Current Carriers | Intermediate Electronics

What makes a semiconductor a semiconductor? For that matter, what makes an insulator an insulator and a conductor a conductor? It all comes down to how much energy it takes to pull an electron away from its nucleus! We delve into this and also talk about how not only electrons move but also the lack of electrons, or holes, move. It’s kinda weird but pretty cool. Check it out!
