SELF ASSEMBLED ONE DIMENSIONAL NANOSTRUCTURES ON Si (001) SURFACES

Abstract

Different kinds of one dimensional nanostructures that self assemble on semiconductor surfaces have been studied experimental and theoretically in recent years. They are interesting not only because of possible applications but also from a fundamental point of view. In basic research the interest is motivated by the possibility to understand interesting physical phenomena that are related to these systems, such as surface stability, growth, and the properties of one-dimensional systems, to mention only a few. For technological applications, they are very important in nanoelectronics, since there is always a search for ways of creating smaller circuits (in the lower tens of nanometers), beyond the capabilities of normal lithography. In this article, we survey some of such systems when grown on the Si(001) surface.
