types of semiconductor devices

I think I touched on this in an answer I provided to one of your other questions regarding electrical components. The major semiconductor devices are:

Diodes
Bipolar Transistors
Field Effect Transistors (FET)

Diodes serve to rectify current...they allow current to pass in only one direction. This allows them to convert alternating current into direct current. They can also be arranged to multiply frequencies through rectification and they can serve as voltage clamps in electronic circuits as well as acting as temperature sensors.

Bipolar transistors and FETs perform very similar functions. They act as amplifiers and electronic switches. Bipolar transistors are usually of NPN or PNP flavors while FETs can be MOSFETs (metal oxide semiconductor field effect transistors) or JFETs (Junction Field Effect Transistor). These are biased a little differently. FETs differ from bipolar transistors in that the gate of the FET uses a voltage with almost 0 current to turn on/off the transistor whereas bipolar transistors use a base current to initiate current flow from collector to emitter.

Finally, there are more exotic semiconductor devices and large collections of the ones described above. Large collections FETs are usually used to implement digital integrated circuits for computer processors and other applications. Bipolar transistors as well as diodes are often used in integrated circuits for analog chips. There are other devices made from semiconductors including Triacs, SCRs, IGBTs, phototransistors, LEDs (light emitting diodes), etc...but they are sort of variations on the diode and transistor (bipolar and FET).

Hope that helps answer your question!

The main streams are te BJT (bipolar junction transistor) and MOSFET (metal-oxide-semiconductor field-effect transistor). There applications are basically everything electronics. From you digital watch or your IPOD to the control of the space shuttle and communication satellites and everything in between.

What you have asked would take a semiconductor manual to answer. You can locate one at any good book store.

Silicon is the base material from which P and N type materials are made, by adding dopants.
