Under special circumstances, however, this resistance can adopt a fixed value that is independent of the basic material properties and &#8220;quantised&#8221; (meaning that it changes in discrete steps rather than continuously). This quantisation of electrical resistance normally occurs within strong magnetic fields and at very low temperatures when electrons move in a two-dimensional fashion. Now, a research team led by the University of G\u00f6ttingen has succeeded in demonstrating this effect at low temperatures in the almost complete absence of a magnetic field in naturally occurring double-layer graphene, which is just two atoms thick. The results of the study have been published in Nature.&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/phys.org\/news\/2021-10-quantum-effect-naturally-graphene.html\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Novel quantum effect discovered in naturally occurring graphene<\/a>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\nSource: Phys.org&#013;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Usually, the electrical resistance of a material depends very much on its physical dimensions and fundamental properties.
