Lithographically patterned graphene

Web13 apr. 2024 · Lithographically patterned nanoseeds are defined on a Ge(001) surface at pitches ranging from 50 to 100 nm, which serve as starting sites for subsequent nanoribbon growth. Rotational self-alignment of the nanoseeds followed by anisotropic growth kinetics causes the resulting nanoribbons to be oriented along each of the equivalent, orthogonal … WebThe most commonly used method involved lithography to pattern the graphene film in nanoscale with a standard electron-beam (e-beam) source to produce individual or aligned arrays of GNRs. However, the e-beam exposure on the graphene surface often causes irradiation-induced damages and degrades the electronic transport properties of GNRs.
