"During the past years, scientists have achieved significant success in the nanoscience and nanotechnology. Nano electronics is one of the major technologies of nanotechnology. Its one of the most powerful and useful study which has helped engineers to implement new properties. it is used for building the nano electronics components just like transistors. Devices and machines are developed at the rate of 100 nanometers which is extremely small and efficient rate for processing. Nano electronics is also known as the disruptive technology because of its various properties.It plays pivotal role in the field of engineering and electronics. Nano electronics make use of scientific methods at atomic scale for developing the nano machines. The main aim is to reduce the size, risk factor and surface areas of the materials and molecules. Machines under nano electronic process under goes the long range of manufacturing steps each with accurate molecular treatment. Nano electronics develop its products and circuits at super miniature level.Over the past four decades, sustained advances in integrated circuit technologies for memory and processors have given us computers with ever more powerful processing capabilities and consumer electronics with ever increasing non-volatile memory capacity. But as device features are pushed towards the deep sub-100-nm regime, the conventional scaling methods of the semiconductor industry face increasing technological and fundamental challenges. For example, device size fluctuations may result in a large spread in device characteristics at the nanoscale, affecting key parameters such as the threshold voltage and on/off currents. Recent development of controlled high-yield assembly of crossed nanowire p–n diodes and FETs has enabled the bottom-up approach to be used for assembly of nanoelectronic circuits, such as logic gates, that ultimately must be integrated together with memory arrays for read/write operations or to build stand-alone processors.
Two-Volume ‘Brig’s Handbook of Methods & Research in NanoElectronics’ presents the comprehensive strategies for nanoelectronics with an emphasis on memories based on the crossbar motif; discusses representative electromechanical and resistance-change memory devices based on carbon nanotube and core–shell nanowire structures, respectively. Focusing on fundamental research in nanowires, which largely boosted the widespread of knowledge among the research society, this handbook is intended to provide an updated review on the applications of various nanoelectronic devices and the associated advancements in synthesis and properties characterization. The expansion of nanoelectronic application areas will require an increased focus on research that considers from the beginning not just the device, but the circuit, architecture, and end application, in addition to the societal implications of devices that may be entrenched in our everyday world. While it will clearly need to continue focus research on new materials and new scientific phenomena for new devices, there will also be a change toward increased research on nanosystems that not only takes advantage of the properties of the devices but also deliberates how to achieve the novel interfaces between multiple devices in new architectures. This will initiate an increased need for design tools and practices that can conduit from the materials level to the system level, along with drive increased interaction between researchers in the basic sciences and those focused on application."
