Molecular Electronics Devices: A Short Review

Molecular electronics has recently attracted a lot of attention due to promising application in nanoscale electronic devices. In this review we highlight recent results in this field, focusing on single organic molecules working as devices and addressing important effects related with electronic transport, such as push pull molecules, sigma or pi bridges, Coulomb blockage, negative differential resistance, molecular radicals, temperature dependence, environment sensibility, strong and weak coupling, quantum interference, coherent and incoherent transport, tunneling regime, switches, and a few applications will be addressed.
