Semiconductors are hard enough to describe with elaborate mathematical tools, is a physical model too much to ask? [Chuck] has designed, printed and explained the workings of a BJT transistor ...

In an NPN transistor, the connection between base and collector is a PN junction, so as you might expect it shares its properties with the PN junction in a diode. A silicon diode starts to conduct ...

"Our work may challenges us to design and build biodevices with even more sophisticated transport characteristics, for instance, one that contains the equivalent of an npn or pnp junction ... in ...

Diodes has introduced a new range of small signal bipolar transistors aimed at load and signal switching applications in a range of portable devices. The NPN and PNP bipolar transistors are available ...
