Title: Direct Imaging of Low-Dimensional Nanostructures

Abstract

Low-dimensional nanostructures are technologically desirable for their novel physical properties, as well as the benefits of packing density due to scale. In quantum computing, an ideal structure might consist of single dopant atoms precisely positioned a few nanometers below a surface [1]. There is also a need for truly atomic-scale interconnects and ancillary structures. However, due to their nanoscale dimensions, the physical properties of nanowires and related structures will depend on the environment in which they are embedded as well as their composition. This problem is particularly relevant for samples grown on ultra-clean surfaces, which may not survive outside of high-vacuum systems or which might be substantially affected by adatoms. The question then arises as to what happens to surface nanostructures or single dopant atoms during encapsulation or overgrowth.
