A comparison of two air-stable molecular n-dopants for C₆₀

We compare two air-stable <em>n</em>-dopants for the fullerene C<sub>60</sub>: AOB and DMBI-POH. Conductivity and Seebeck coefficient measurements were performed at various doping concentrations and the thermal activation of the conductivity was determined. A superlinear incr...

সংক্ষিপ্ত:We compare two air-stable <em>n</em>-dopants for the fullerene C<sub>60</sub>: AOB and DMBI-POH. Conductivity and Seebeck coefficient measurements were performed at various doping concentrations and the thermal activation of the conductivity was determined. A superlinear increase of conductivity upon doping was found for DMBI-POH doped C<sub>60</sub> reaching a maximum conductivity of 5.3 S/cm. In contrast to this, a linear rise of conductivity and an exponential thermal activation of mobility was observed for C<sub>60</sub> doped by AOB. This suggests a different doping mechanism for the two compounds. © 2012 Elsevier B.V. All rights reserved.
