What does "NPN" or "PNP" mean in terms of a transistor? "NPN" and "PNP" refer to the arrangement of the different types of semiconductor material in a Bipolar Junction Transistor (BJT). In an NPN ...

[Chuck] has designed, printed and explained the workings of a BJT transistor using a 3D printed model. We really like this model because it goes a long way to shed light on some of the more subtle ...

Also called a "bipolar junction transistor" (BJT), it is one of two major transistor categories; the other is "field-effect transistor" (FET). Although the first transistor was bipolar and the ...

The team led by Associate Professor Mario Lanza from the Department of Materials Science and Engineering in the College of ...

In this module on BJTs (bipolar junction transistors), we will cover the following topics: BJT Device structures, Energy band diagrams, Active bias, Leakage current, Recombination in base, Hoe ...

Advances in materials and architecture could lead to silicon-free chip manufacturing thanks to a new type of transistor.

The first transistor was about half an inch high. That's mammoth by today's standards, when 7 million transistors can fit on a single computer chip. It was nevertheless an amazing piece of technology.
