The p-n-p transistor is made by placing an n-type material between two p-type materials. All these components are built on a base of the semiconducting material silicon. This transistor concept was ...

When a semiconductor includes both N-type and P-type materials, it is called a complementary metal-oxide semiconductor (CMOS, pronounced "sea-moss"). How Are Semiconductors Made?

The use of n-type and p-type silicon is a foundation concept in the design of transistors. Pure silicon is not conductive. However, it can be made conductive by adding other elements to its ...

50 years ago this year, in its ‘Patent Pointers’ section, the Electronics Weekly edition of September 14 th 1960 carried the following snippet. ‘An ingenious way of making a P-N-P-N or an N-P-N-P ...

Schematic representations of (a) n-p-n transistor and p-n-p transistor, and (b) Symbols for n-p-n and p-n-p transistors. Relation between Ic, Ib and Ie Current transfer ratio current amplification ...

Here we propose, for the first time, a solar cell characterized by a semiconductor transistor structure (n/p/n or p/n/p) where the base–emitter junction is made of a high-bandgap semiconductor ...

The p-n junction is formed by creating a region of p-type (with positive charge carriers called holes) next to an n-type region within the same semiconductor material.

A group of Korean researchers have recently succeeded in developing new p-type semiconductor materials and thin-film transistors that will lead the innovation of the semiconductor industry. These ...

Choice of P-N junction device. Even though a diode can be used to measure temperature, a diode connected PNP or NPN is preferred. The ideality factor of a diode is up to twice as large as a diode ...

This second course provides a more detailed description of high-voltage Schottky and p-n diodes, starting with the semiconductor physics background needed to analyze both types of diodes. ... Module 3 ...
