WebMay 21, 2014 · Abstract. The contact conductance and the apparent barrier height ϕ of graphene on Ir (111) are measured with a cryogenic scanning tunneling microscope. A strong dependence of ϕ on the tip–sample distance is found and explained by a local lifting of the graphene film by van-der-Waals forces. Variations of ϕ observed within the moiré … WebMar 6, 2013 · But the integral function starts to fall apart after 6 hours, as in the problem pictures above show, because of how Graphite aggregates data.
