Fig. 2. ID–VD output characteristic curves at (a) T = 300 K and (b) T = 420 K for different VG conditions. Inset: Extended view of (a) and (b). (c) VD-dependent Y function method (YFM) (lines) at T = 300 K and the corresponding fitting curves (dotted lines). (d) Width-normalized VD-dependent contact and channel resistance, and (e) their effective contribution ratio to total resistance at T = 300 K. (f) VD-dependent EA as a function of VG, determined by fitting G(T) to a thermal activation transport model.
