As a matter of fact, in all areas there is a facilitator or protector ie semiconductor. Semiconductor materials have electrical conductivity that deteriorates between channels, for example, copper, gold, etc. and protection, for example, glass. Their barriers decrease when their temperature is built, which behaves counteracting metal. Their lifting characteristics can be modified in a way that helps with the delivery of the goal (“doping”) into the crystal structure. Where two different doped areas exist in the same gems, semiconductor junction is created. Responsibility of charge carriers including electrons, particles and electron gaps at these intersections are important diodes, transistors and all sophisticated hardware.
