One of these materials - silicon - is making it possible for you to read these words right now! That's because silicon is the essential material in an electronic computer chip. Semiconductor means a material can conduct electricity with a bit of help in the form of added impurities..
The materials most often used in semiconductor devices are germanium and silicon. Germanium has higher electrical conductivity (less resistance to current flow) than silicon, and is used in most low and mediumpower diodes and transistors.Silicon is more suitable for highpower devices than germanium.he materials most often used in semiconductor devices are germanium and silicon.
