Transistors can also be thought of as switches that turn on or off the flow of electrons.
At this level, and as transistors get smaller and smaller, we find ourselves nearing the tiny scales dictated by quantum physics.
Right now, a transistor can be about 40 nanometers or smaller, almost 500x smaller than an average cell in your body.

Right now, a transistor can be about 40 nanometers or smaller, almost 500x smaller than an average cell in your body.
Essentially, transistors are operating at nearly an atom’s scale.
At this level, the electrons don’t need to flow — they can just move using “quantum tunneling”.
