VON KLITZING CONSTANT Meaning and Definition

  1. The von Klitzing constant, symbolized as RK, is a fundamental constant in physics that is related to the quantization of electrical resistance. It is named after Klaus von Klitzing, a German physicist who discovered the quantized Hall effect in 1980, for which he was awarded the Nobel Prize in Physics in 1985.

    The von Klitzing constant is defined as the resistance that a two-dimensional electron system exhibits when subjected to a magnetic field perpendicular to its plane. It is equal to approximately 25,812.807 ohms, precisely defined as h/e^2, where h is the Planck constant and e is the elementary charge.

    The significance of the von Klitzing constant lies in its association with the quantum Hall effect, which is a phenomenon that occurs in certain materials at very low temperatures and strong magnetic fields. In these conditions, the quantization of electrical resistance is observed, meaning that the resistance takes on discrete values that are exact multiples of the von Klitzing constant.

    The von Klitzing constant provides a precise standard for resistance in quantum metrology and is used in the calibration of resistance standards. It also plays a crucial role in the International System of Units (SI) as it underpins the definition of the ohm, which is the unit of electrical resistance.
