FIG. 1.

(Color online) (a) Room temperature resistivity (ρ 300K) of composite CoPc-FePc films as a function of FePc concentration. (b) The temperature dependence of resistivity for the CoPc, FePc, and composite CoPc-FePc films (c) Plots of reduced activation energy W( = −dln[ρ(T)]/dlnT) for CoPc, FePc, and composite CoPc-FePc films. (d) Linear fit of conductivity versus T 3/2 data for composite CoPc-FePc films. Inset shows the nearly linear dependence of log ρ versus log T plots for CoPc and FePc films.

FIG. 2.

(Color online) (a) Log-log plots showing current-voltage (J-V) characteristics of composite films in the temperature range 300-50 K. (b) Temperature dependence of mobility for composite films. (c) Log-log plots showing current-voltage (J-V) characteristics of CoPc films in the temperature range 300-100 K. (d) Power law fit of data of (b). The fits meet at cross over voltage V c = 1368 V. Inset shows the temperature dependence of voltage exponent (α).
