WebbThis sounds like a resistor, and indeed it is possible to make resistors from semiconductor material. However, in electronics, semiconductor has a more specific meaning. If we take a crystal of some pure material, such as silicon, we find that each silicon atom has four bonds (this is called the valency of the atom), and each bond links … WebbThe resistance of the resistor is inversely proportional to this cross sectional area. But there's one more quantity that this resistance could depend on, and that's what the material is actually made of. So, the geometry determines the resistance as well as what the material is made of. Some materials just naturally offer more resistance than ...
