Descripció
Sumari:The use of molecules as electronic components has marked a trend of miniaturization in devices known as molecular electronics. It has been performed theoretical calculations of the quantum transmission coefficient and the electric current through a molecule of benzene connected to electrical terminals. The transmission coefficient is obtained by recursively calculating the Green function of the system. The influence of a small movable gate SMG on the transmission is also modeled. The results show that the transmission coefficient oscillates as a function of the incident energy of the electrons, and the electric current shows that the benzene molecule has a semiconductor character. The oscillations in the transmission can be manipulated either by the position of the terminals in the molecule or influence of the SMG in a region close to a particular atom.
