Molecular electronics is perceived as a guaranteeing nomination to the nano-electronics of the future. It can offer solutions for the ultimate scaling down issue in nano-electronics. Molecular electronics can be anticipated as a workable and sensible route to amass extensive numbers of nanoscale questions (molecules, nanoparticles, nanotubes and nanowires) to structure new devices and circuit architecture. Its semiconductor nanowires NW represent a perfect framework for investigating low dimensional material science and are expected to play an important role as both interconnects and functional device elements in nanoscale electronic and optoelectronic devices.

Sub-molecular electronics, i.e., data transforming toward the molecular-scale, are increasingly investigated as guaranteeing benefits in the nano-electronics of the future. Person meaning is the data transforming utilizing photo-, electro-, ionic magneto-, thermo-, mechanic- or chemo-active impacts structurally. This definition excludes devices dependent upon thicker organic polymer materials, alluded as organic electronics. In this chapter, a short diagram of the nanofabrication of leading polymer nanomaterials is offered, then the electronic properties of few fundamental devices are audited starting with basic particles, such as molecular wires. The fast scaling down of electronics of the submicron scale has prompted momentous expansions to registering power. As a rule, coordinated circuit nano-electronics will oblige conceptually new device fabricating blocks, versatile circlet architectures and, in a far-reaching way, the distinctive creation methodologies. Characterized nanoscale building-blocks have the possibility of try significantly past the breaking points of top-flight engineering organization by characterizing magic nanometer-scale measurements through concoction amalgamation (Bumm & Arnold, 1996). Past investigations have prompted an expansive extent of proof-of-concept nanoscale devices, including diodes and transistors dependent upon distinctive organic polymer molecules, quantum spots or carbon nanotubes (NTs) (Patrone et al., 2003). However, these investigations about distinctive nano-devices represent just an introductory step to nano-electronic circuits. It remains an incredible challenge to development from a single device level to the functional circuit level because of the following reasons: (1) the insufficient control of the properties of individual building blocks, (2) low device-to-device reproducibility, (3) the absence of dependable techniques for proficiently amassing and coordinating fabricating pieces under device arrays and circuits.

Next, the discussion of new nanoscale electronic device ideas includes polymer transistors, crossed NW p-n diode and crossed NW field effect transistors (FETs). Proliferation gathering of these versatile crossed NW device components empowers an inventory of coordinated structures. Organic transistor backplanes are ideally suitable to electronic paper applications and different presentation schemes. Low-cost and processing advantages, in addition to moving forward execution have prompted organic-based radio frequency identification tag advancement. The chemical interaction between various organic and polymer semiconductors can be exploited in chemical and biological sensors based upon organic transistors. Recently, a fascinating methodology of molecular electronics as resistive memory and sub-molecular level RAM has emerged in this field with an extensive range of investigations. The point portrayal of an extensive variety of photonic and optoelectronic devices, including nanoscale light-emitting diodes LEDs and incorporated nano-LEDs, concerning illustration organic vast scale coordinated circuit circuits has been executed for this methodology (Fiore et al., 2002).
