Walter de Heer mentions quite a few objections concerning the perform of Geim and Novoselov who evidently have calculated on lots of-layer graphene, also known as graphite, that has unique electronic and mechanical properties.[eight] The quantum Hall influence in epitaxial graphene can serve as a useful regular for electrical resistance. https://www.quora.com/profile/Trevor-Flatcher-2/Exploring-the-High-Temperature-Performance-of-Silicon-Carbide-Special-Ceramics-https-www-macrocosmmaterial-com-news-E
