| Abstract | We compare two air-stable n-dopants for the fullerene C60: 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 C60 reaching a maximum conductivity of 5.3S/cm. In contrast to this, a linear rise of conductivity and an exponential thermal activation of mobility was observed for C60 doped by AOB. This suggests a different doping mechanism for the two compounds. |
