“…1, showing the typical variation in amplication in emission current (density), h ¼ (J treated max /J pristine max ), and reduction in turn-on and threshold elds, 3 ¼ (E treated on,thr /E pristine on,thr ), for the various low dimensional graphitic allotropes (Fig. 1(a)), including graphene, 29,30 carbon nanotubes (CNT), 19,21,22,24,27,28,[31][32][33][34][35] and carbon nanobres (CNF) 36,37 as a function of plasma precursor type, plasma power, and exposure time. Here, the subscript 'max' denotes the maximum measured current density, with the threshold electric eld (E thr ) and the turn-on electric eld (E on ) of the normalised current density, dened as 10% and 30% respectively.…”
