Abstract

C60 is an important electronic material and its properties can be tuned by thermal annealing process and solid phase crystallization process. These properties were investigated as a function of thermal annealing temperature and solid phase crystallization. However there is no systematical study on annealing effect and Solid Phase Crystallization of C60 films. In this study, the effect of thermal annealing on formation of nanocrystalline C60 thin films were investigated for annealed samples and solid phase crystallized samples. The C60 films described here were prepared by vacuum thermal evaporation method. The structural properties of C60 films were investigated with Raman spectroscopy. The electrical properties of C60 films were investigated with current-voltage characteristics and electrical conductivity -temperature measurements. The result indicated that the thermal annealing and solid phase crystallization process bring structural changes in the C60 films and that resulted in change in electrical properties. The performance of the electrical properties was varied because of the transfer of the structural properties by thermal annealing and solid phase crystallization.
