Nanoelectronics refers to the field of study which is concerned with understanding, exploring and exploiting the characteristics of devices and instruments, which have directional dimensions at the nanoscale. Its one of the most powerful and useful study which has helped engineers to implement new properties. It is used for building the nanoelectronics components just like transistors. Devices and machines are developed at the rate of 100 nanometers which is extremely small and efficient rate for processing. Nanoelectronics is also known as the disruptive technology because of its various properties.
