quantum Hall effect

[′kwän·təm ′hȯl i‚fekt]
(electronics)
A phenomenon exhibited by certain semiconductor devices at low temperatures and high magnetic fields, whereby the Hall resistance becomes precisely equal to (h / e 2)/ n, where h is Planck's constant, e is the electronic charge, and n is either an integer or a rational fraction. Also known as von Klitzing effect.

Breakthrough in developing graphene may lead to high-speed electronics in future
Placing graphene samples in magnetic fields whose intensities the researchers ratcheted up, they saw the electrical resistance increasing in discrete steps, a phenomenon known as the quantum Hall effect. Around the same time, a group led by Philip Kim of Columbia University made the same discovery after learning of Geim's tape-peeling technique.
