GNR-based devices are promising candidates for next-generation electronic, spintronic, and thermoelectric applications. However, a significant portion of the GNRs synthe- sized to date are unstable under ambient conditions and require protection from the environment. Here, we encapsulate 9-atom wide armchair GNRs (9-AGNRs) in hexagonal boron-nitride (h−BN) and contact them using metallic edge contacts. At 9 K, quantum dot (QD) behavior with well-defined Coulomb diamonds (CDs) is observed, with addition energies in the range of 16 to 400 meV. For increasing temperatures, charge transport through the 9-AGNR film, occur- ring via a combination of temperature-activated hopping and polaron-assisted tunneling, starts to dominate, with a crossover between QD transport and film transport occurring at around 100 K. At room temperature, our short-channel field-effect transistor devices exhibit on/off ratios as high as 3×10^5. Overall, our work demonstrates that 9-AGNRs can be contacted while being encapsulated in h−BN. This strategy opens the way for a whole range of GNRs candidates that are unstable under ambient conditions to be incorporated into electronic and spintronic devices. description_type: abstract lang: und ## Creator - name: Wenhao Huang role: author - name: Oliver Braun role: author - name: David I.
