Electronic transport through CNT-fluorographene-Au junction: First-principles study

Quantum transport through CNT-fluorographene-Ag junction is studied using density functional theory in combination with the Landauer-Büttiker formalism. Rectifying behavior is obtained for both single and bilayer fluorographene with rectification ratio exceeding 4. The asymmetric conductance originates from bias-dependent charge localization in the system as was revealed in transmission eigenstates analysis. These findings can be useful in developing metal-insulator-metal junctions for high-frequency applications.
