n-type semiconductor - A semiconductor compound formed by doping an intrinsic semiconductor with a pentavalent element. An n-type material contains an excess of conduction band electrons.
semiconductor - An element which is neither a good conductor or a good insulator, but rather lies somewhere between the two. Characterized by a valence shell containing four electrons. Silicon, germanium and carbon are the semiconductors most frequently used in electronics.

Quick Voltage Dropper
Quick Voltage Dropper If you fliped through our section on semiconductors you might have noticed that silicon diodes need at least 0.6 volts to work and reduce the voltage by 0.6 volts. So we can tak


Transistors
Transistors Transistors are semiconductors that control current flow. They have three contacts and a small current at one contact can control a much larger current flowing through the other two conta

Diodes
Diodes Diodes are one of the most common semiconductor devices. As we know from the last page, both N and P type silicon conduct electricity. The conductivity (or resistance) of both is by how doped

Semiconductors
Semiconductors Semiconductors are quite possible one of the most important things in the modern world. The are made from crystals and can act as conductors or insulators in different circumstances.
