Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Nanoelectronics refer to the use of nanotechnology on electronic components, especially transistors. Although the term nanotechnology is generally defined as utilizing technology less than 100 nm in size, nanoelectronics often refer to transistor devices that are so small that inter-atomic interactions and quantum mechanical properties need to be studied extensively. Nanoelectronics are sometimes considered as disruptive technology because present candidates are significantly different from traditional transistors. Some of these candidates include hybrid molecular/semiconductor electronics, one dimensional nanotubes/nanowires, or advanced molecular electronics. Learn more about nanoelectronics, its branches and applications in this book.
