Definition: | macroscopic quantum effect, occurring at low temperature in a two-dimensional system of high-mobility electrons or holes, in which an applied magnetic field induces between two points a voltage, the quotient of which by the electric current through a line joining the two points assumes, over certain high-value ranges of the magnetic flux density, quantized plateau values equal to R_{K}/n, where R_{K} = h/e^{2} is the von Klitzing constant and n an integer, h being the Planck constant and e the elementary electric charge
NOTE – The quotient of the voltage by the electric current is called Hall resistance. The value of the von Klitzing constant is 25 812,807 557(18) Ω (CODATA, 2006). | ||
