One form of this phenomenon involves tying cyclotron frequencies to degenerate Landau levels, and is performed on gallium arsenide interfaces, although it was recently discovered in room-temperature graphene. A class of low-impulse spacecraft ion thrusters are based on and named for this phenomenon. A filling factor for a type of this phenomenon multiplies a standardized resistance. That factor was found to take on rational values, which earned K
One form of this phenomenon involves tying cyclotron frequencies to degenerate Landau levels, and is performed on gallium arsenide interfaces, although it was recently discovered in room-temperature graphene. A class of low-impulse spacecraft ion thrusters are based on and named for this phenomenon. A filling factor for a type of this phenomenon multiplies a standardized resistance. That factor was found to take on rational values, which earned Klaus von Klitzing the Nobel Prize. The inverse of the carrier density is proportional to this effect's namesake coefficient. For 10 points, name this physical effect, the voltage difference across a conductor in a magnetic field.
