Product description

To observe the fractional quantum Hall effect, in which the filling factor turns out to be a fractional number rather than an integer, it is necessary that the Coulomb interaction U between electrons be significantly greater than their kinetic energy E. Estimate how much the electron density in a two-dimensional electron gas must be changed so that the ratio U /E increased 10 times?
