Is graphene prone to oxidation and water absorption in open air? Does graphene's quality degrade? how does oxidation and water adsorption affect it properties? can oxygen chemically adsorb on graphene? Does water penetrate into graphene layers?
what factors affect an epitaxial film's lattice matching and dislocation densities? Are there any possible ways to reduce lattice mismatch and dislocations in various deposition techniques?
