If
you have no interest in how the electrical devices which aid and govern
every area of modern life actually work, you won’t know a thing about
semi-conductors. Their name is apt, for they are a vital but silent
partner in the business of living. Without them, many of our biggest
industries simply couldn’t survive. We wouldn’t have cheap, readily
available electronic goods. Even life-saving diagnostic tools would be
lost to modern medicine without the semi-conductor.
If you’re still on board, let’s get the science bit done. To understand semi conductors
– visit RS Components to survey all manner them - you have to
understand conductors. Even the technophobes among us can grasp the
concept of materials which conduct electricity. In most of our computers
and gadgets, conductors are made of metal, while non-conductors are
usually made of ceramics. A semi-conductor is a material which conducts
energy between conductors and non-conductors. They are either made of
elemental materials such as germanium and silicon, or compounds like
cadmium selenide. Compounds are made using a process known as doping, in
which small impurities are added to silicon, enabling it to properly
channel the electrical flow.
