[4] Llinas, J. et al., “Short-channel field-effect transistors with 9-atom and 13-atom wide graphene nanoribbons.” Nature Communications (2024). TīmeklisUniaxial strains are introduced into individual graphene nanoribbons (GNRs) with highly smooth edges to investigate the strain effects on Raman spectroscopic and electrical properties of GNRs. It is found that uniaxial strain downshifts the Raman G-band frequency of GNRs linearly and tunes their bandgap significantly in a non-monotonic … totaled car title
