Defect Engineering in 2D Materials: Precise Manipulation and Improved Functionalities

Figure 1

Generation and manipulation of defects in 2D materials by e-beam. (a) Creation of vacancies in graphene under 80 keV e-beam irradiation. (b) Electron beam-driven divacancy migration observed at 80 keV. Reproduced from [30]. (c) Configurational changes of flower defect via C-C bond rotations in graphene. Reproduced from [31]. (d) Oscillations of a W atom between two trapping centers 1 and 2 on a few-layer graphene at 480°C. Reproduced from [33]. (e) e-beam manipulation of a Si atom around a single hexagon in graphene. Reproduced from [37].
