Abstract: Zest to sustain Moore’s Law paved way for CMOS technology that has evolved from microelectronics to nanoelectronics. Further miniaturization is being limited in silicon based CMOS. Hence, alternative materials are being studied for use in electronic devices. Molecules are a very promising candidate. Molecular Electronics promise not only miniaturization but also property self assembly. Molecular electronics is visualized as the future of electronics. Apart from being the solution to the miniaturization problem, it also promises the possibility to assemble a large number of nanoscale objects to form new devices. Here, we discuss the basics of molecular electronics, its components and some of its applications.
