Silicon semiconductors are classified into two categories based on the type of impurity used for doping: n-type, where electrons flow out, and p-type, where electrons flow in. Regardless of the type, ...

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 ...

William Shockley improved on this design with his junction transistor, a three-layer sandwich of different types of semiconductor. The diagram illustrates the basic design of an NPN junction ...

When we were in school, every description of how transistors work was pretty dry and had a lot of math involved. We suppose you might have had a great instructor who was able to explain things ...

CMOS technology combines two types of transistors that work together, leading to efficient power use and high noise immunity. CMOS technology uses two different types of transistors, n-type (nMOS) and ...

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.
