摘要
低带隙聚合物聚-4-二氨基亚甲基- 4h -环戊[2,1-b;3,4,b ']二噻吩的原位电导率测量结果显示，p型和n型电导率都是电势的函数。在p-掺杂和n-掺杂的形式电位之间的电势处，电导率最小，产生的本征电导率为1.0 × 10−8 S cm−1，与光学带隙0.8 eV一致。
In situ conductivity of a low band-gap conducting polymer: Measurement of intrinsic conductivity
In situ conductivity measurements on the low band-gap polymer, poly-4-dicyanomethylene-4H-cyclopenta[2,1-b;3,4,b′]dithiophene have provided both p- and n-type conductivities as a function of the potential. A minimum in the conductivity, at a potential between the formal potentials for p- and n-doping, yields an intrinsic conductivity of 1.0 × 10−8 S cm−1, consistent with the optical band-gap of ∼0.8 eV.
