Temperature dependence of I–V characteristics of C60 molecule: A Green´s function approach

Making use of a generalized Green´s function technique and Landauer formalism, the temperature depended current-voltage (I-V) characteristics of C₆₀ molecule, sandwiched between two metallic electrodes are numerically investigated. In addition, the influence of the electron-phonon coupling strength on the electronic properties of the molecule is studied. The I-V characteristics of the molecule are determined in two temperature limits, T = 3K and T = 300K. Our results indicate that the molecule primarily act as a semiconductor in lower temperatures but moves toward becoming an ohmic-like conductor when the temperature increased to the higher magnitudes.
