Understanding the effects of downscaling the device dimensions to the nanometer size is one of the most important topics in the modern material science applied to microelectronics. In fact, the confinement of electrons in dimensions typical of atoms and molecules obliges to consider their quantum behavior. Therefore, a particular class of effects is characterizing ultrascaled devices. In the previous years, these ideas led to the birth of the “nanotechnology and nanoelectronic revolution” 1, 2 with the aim to understand the effects of downscaling the matter in the atomic range and to develop innovative nanostructured materials and quantum effects based devices 1, 3 following a bottom-up procedure with respect to the traditional top-down scaling scheme. In particular, the nanometric level knowledge of the structural characteristics of such innovative materials and the nanometric control and manipulation of these …
