Nanoelectronics refers 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 sometimes refers to transistor devices that are so small that inter-atomic interactions and quantum mechanical properties need to be studied extensively.
In this tutorial various effects that occur at the nanoscale will be reviewed. Emphasis will be placed on how different physical phenomena that occur at the nanoscale are successfully modeled. In that context bandstructure effects, choice of the proper transport kernels and coupling to efficient Poisson equation solvers will be discussed. The importance of Computational Electronics in the context of efficient design process of nanoscale devices and nanoscale structures in general, will be highlighted.
