conductors

A team of researchers at Georgia Tech have discovered a way to use graphene to transport electrons with virtually no resistance. Known as ballistic transport, this property is accomplished when electrons travel through graphene nanoribbons and behave more like optical waveguides or quantum dots.

When people are asked what is the most commonly used component in electrical or electronic circuits, the typical answers are “Well, of course everyone knows its resistors”, or “It must be capacitors”, and even sometimes “Nothing operates without transistors”. In fact, none of those answers are correct; the real answer is that conductors are the most common type of component.
