摘要

We outline the scrutiny of the two probe devices formed by placing the nonclassical fullerene molecules C-M (20 <= M <= 30) within semi-infinite gold electrodes using density functional theory. The electronic structure and molecular orbitals of isolated fullerene molecules are broadened to form junction devices with charge injection at zero as well as variegated bias respectively. The molecular junctions thus formed are contemplated for two important electrical constitutions, current, and conductance. These parameters are then elaborated and contemplated for their electronic parameters namely, the density of states, transmission coefficient, molecular orbitals, molecular projected self-consistent Hamiltonian states, electron density, and Mulliken population. We conclude that C-20 and C-24 fullerene molecule exhibits extremely metallic behavior while others fail to demonstrate such behavior. The molecular device, thus formed, strongly supports the superconductive behavior of the C-24 molecule with an ability to easily adapt by modulating its active molecular orbitals under applied potential.
