“…If one tries this, in spite of the fibrillar morphology shown in figures 5, a value of# ,~ 102cm2V -l s -1 is obtained [87]. This value is two orders of magnitude higher than the one we would obtain from the conductivity tr = N#e by estimating N from the doping concentration.…”

“…In figure 57 the resistance change in fields up to 7 T is shown for various iodine-doped samples at liquid-helium temperature [87]. The most remarkable result is the negative magnetoresistance in highly doped samples, but up to now this effect has not yet contributed to a better understanding of charge transport in polymers.…”

“…For example, the iodine doping levels of cis -polyacetylene can be tuned from 2.2 mol% to 18.7 mol% to obtain conductivities ranging from 10 2 S cm −1 to 10 −1 S cm −1 , respectively. 19,20…”

“…[2][3][4][5][6][7][8][9][10][11][12][13] In early measurements, both positive and negative magnetoresistance data were reported. [2][3][4][5] After the synthesis of high-density films which are known to have much less defects, 14,15 more systematic studies have been carried out intensively to see the role of dopants, backbone chains and the interchain interaction in the conduction process. [6][7][8][9][10][11][12][13] It was revealed that the negative magnetoresistance of a highly conducting sample changes to be positive as the sample becomes aged.…”
