In the last 50 years, Moore's law has fueled the development of the computing field. Nowadays, skyrocketing fabrication costs and increasing demand for miniaturization, high performance and low power consumption are becoming incredibly challenging, pushing the research effort towards Beyond-CMOS technologies and innovative architectural solutions. In this scenario, molecular electronics paves the way for smart and cheap technological processes based on self-assembly. The possibility to produce artificial molecules with nano-scaled dimensions and engineered properties, is really attractive, since enables extremely high integration with fewer power issues accomplishing a variety of electronic tasks, including conducting wire, rectification, memory, sensor and switching only by simply changing the type of molecule.
