Abstract
- Scientific research shows that quasiparticles of the fractional quantum Hall effect have a fractional charge. Experiments used a quantum point contact, achieved through pinching together the ends of an electron gas, to create a week tunnelling current. The paths of flowing currents at quantum points are shown. External circuitry noise was filtered out.
