This effect was first identified in the inversion layer of a MOSFET by a man who noticed that a plot of voltage versus magnetic field strength showed several plateaus.
The discovery of this effect was announced in a paper in which Michael Pepper and Gerhard Dorda were two of the three authors. The topological nature of this effect can be understood in terms of Fredholm indices and Chern numbers. The only known physical objects that can be considered anyons exhibit one form of this effect. That same form of this effect was discovered by Tsui and Stormer, and is seen at the electron Landau level filling fractions. This effect is used to define a standard of resistance as well as to give a very accurate determination of the fine-structure constant. This effect was first identified in the inversion layer of a MOSFET by a man who noticed that a plot of voltage versus magnetic field strength showed several plateaus. For 10 points, name this effect that was discovered by Klaus von Klitzing.
