What Is Resistance Resistivity of Materials?

Superconductors are materials where electrons do flow freely through the material they don't get scattered by anything. They have essentially zero resistance and can zoom right through so there's a limited amount of current when you put a certain voltage on them. The key elements of these things called field field effect transistors in an electronic circuit is made from semiconductors. These this idea of doping where you put other materials other into semiconductors changes where the conduction band is it's a slightly longer story but in the end  in a in a CPU the the sort of the key elements ofthese things call field field Effect Transistors (FETs) that make up today's modern processors.
