| 中文摘要 | we report the measurements of conductivity, i-v curve, and magnetoresistance of a single au/polyaniline microfiber with a core-shell structure, on which a pair of platinum microleads was attached by focused ion beam. the au/polyaniline microfiber shows a much higher conductivity (similar to 110 s/cm at 300 k) and a much weaker temperature dependence of resistance [r(4 k)/r(300 k)=5.1] as compared with those of a single polyaniline microtube [sigma(rt)=30-40 s/cm and r(4 k)/r(300 k)=16.2]. the power-law dependence of r(t)proportional to t-beta, with beta=0.38, indicates that the measured au/polyaniline microfiber is lying in the critical regime of the metal-insulator transition. in addition, the microfiber shows a h-2 dependent positive magnetoresistance at 2, 4, and 6 k. |
