Walter de Heer mentions quite a few objections regarding the perform of Geim and Novoselov who apparently have calculated on several-layer graphene, also called graphite, that has diverse electronic and mechanical properties.[8] The leading advantage of epitaxial graphene growth on silicon carbide more than other techniques is to acquire graphene https://www.quora.com/profile/Trevor-Flatcher-2/Key-Applications-of-Silicon-Carbide-in-the-Aerospace-Industry-Silicon-Carbide-SiC-has-emerged-as-a-crucial-material-i
