How Diodes Work – An Introduction

This post explores the basics of how diodes work.

A diode is the most basic useful semiconductor device. It has two leads and acts as a one-way gate for electric current. Diodes have a multitude of uses, some of which we’ll touch on later.

We’ll start our tutorial on how diodes work with a very quick overview of basic semiconductor physics. This will serve as the basis for which all diodes work.
