“…Using values of e = 3.53 [15],m %10 À7 m 2 V À1 s À1 [20], and N v % 10 27 m À3 [21], the E t and N t values are found to be 0.11 eV and 1.53 Â 10 25 m À3 , respectively. The value of N t is comparable with those observed on cobalt phthalocyanine [22], nickel phthalocyanine [23] and PbPc [24] i.e., 1.5 Â 10 25 m À3 , 7.8 Â 10 25 m À3 and 5.18 Â 10 25 m À3 , respectively. The series resistance, R s , is an important parameter since it affects the electrical characteristics of the rectifying contacts.…”
