Quantum Wires and Dots: The Challenge to Fabrication Technology
In these lectures I will argue that the fabrication of quantum dots and wires for optical applications presents the severest challenge to semiconductor nanotechnology. The dimensional requirements of these structures coincide with a variety of limitations in lithography and pattern transfer processes which are either fundamental or show few signs of being overcome. As a result, researchers in this field are seeking alternative, novel and in some cases bizarre ways of making quantum structures which raise important questions about our approach to device fabrication and bring microelectronics directly into the realm of molecular electronics and related issues.
