Transporte electrónico Función de Green Corriente eléctrica Benceno Electrónica molecular Electrodo móvil puntual. 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. El uso de moléculas como componentes electrónicos ha marcado una tendencia de miniaturización en dispositivos conocida como electrónica molecular. En este trabajo se realizan cálculos teóricos del coeficiente de transmisión cuántico y la corriente eléctrica a través de una molécula de benceno conectada a terminales eléctricas. El coeficiente de transmisión es obtenido mediante el cálculo recursivo de la función de Green del sistema. Se modela también la influencia de un electrodo móvil puntual (small movable gate SMG) sobre la transmisión. Los resultados muestran que el coeficiente de transmisión oscila como función de la energía incidente de los electrones, y la corriente eléctrica muestra que la molécula de benceno tiene un carácter semiconductor. Las oscilaciones en la transmisión pueden ser manipuladas por la posición de las terminales en la molécula y por la influencia del SMG en una región cercana a un átomo en particular.
