How Does a Diode Work? Intro to Semiconductors (p-n Junctions in the Hood) | Doc Physics

Описание к видео How Does a Diode Work? Intro to Semiconductors (p-n Junctions in the Hood) | Doc Physics

We will see what a diode does, and then begin to understand why. We'll investigate the structure of silicon and other group (IV) elements. We will discuss doping and other methods of creating mobile charge carriers like electrons and holes. We will finally discover that when p-type silicon is next to n-type silicon, a region of "space charge" or "depletion" is formed. Unfortunately, that region prevents the flow of charge. In order to turn on the diode, we'll have to shrink that built-in electrical potential.

Oh, and the thugs are the guys who lift up the parking garage to make the cars flow. If you were wondering...
