In this lesson, students build two circuits and explore how transistors function. When Bell Labs introduced the transistor in June of 1948, a spokesman proudly announced "This cylindrical object . . .

A single electron makes the difference between “on” and “off” for a new transistor made from a single carbon nanotube, whose minute size and low-energy requirements should make it an ideal device for ...

OK, so I have an old project laptop with an IDE/PATA/slim-ATAPI optical drive bay, into which I have inserted a SATA drive caddy with a bridge board. The thing is, the caddy doesn't transfer the drive ...

If you’ve ever wished you had a faster phone, computer, or internet connection, you’ve encountered the personal experience of hitting a limit of technology. But there might be help on the way. Over ...

1. What is a semiconductor? Generally speaking, the term semiconductor refers to a material—like silicon—that can conduct electricity much better than an insulator such as glass, but not as well as ...
