By placing two PN junctions together we can create a bipolar junction transistor. In a PNP transistor the majority charger carriers are holes and typically germanium is favored for these devices. In NPN transistors the majority charger carriers are electrons; … Read more

The Basics of Semiconductor Physics as the Foundation of Electronics
Metals have a large number of weakly bound electrons in what is called their conduction band. When an electric field is applied to a metal such as copper, the electrons migrate freely producing a current through the metal. Because of … Read more
