Observation of the quantum Hall effect in epitaxial graphene on SiC(0001) with oxygen adsorption

E. Pallecchi, M. Ridene, D. Kazazis +5

In this letter we report on transport measurements of epitaxial graphene on SiC(0001) with oxygen adsorption. In a $50\times 50\mu {\mathrm{m}}^2$ size Hall bar we observe the half-int…
