"Semiconducting Nanowires - beauty in 1D"

Abstract.  Semiconducting nanowires have sparked enormous interest worldwide. Their novel 1D structures, interesting properties, and potential applications beautifully illustrate many important aspects of nanoscale materials. In this presentation I will give an overview of semiconducting nanowires with an emphasis on the Si/Ge system. Examples of nanowire studies will serve to illustrate the rich and wide range of materials science which occurs at the nanoscale. A key challenge in the eventual application of most nanoscale materials is their integration across multiple length scales and into larger systems. These integration challenges for nanowires will be discussed. I will finish by highlighting the recent interest and potential advantages of nanowires in energy harvesting and storage applications.

Bio. Tom Picraux studies electronic thin film and nanostructured materials. He received the DOEs E.O. Lawrence Award for materials research, a Fulbright Fellowship in Physics at Cambridge University, is past Chair of the American Physical Societys Materials Physics Division, past President of the Materials Research Society, and a Fellow of the American Physical Society and American Association for the Advancement of Science. He currently holds joint appointments as chief scientist for the Center for Integrated Nanotechnologies at Los Alamos National Laboratory and research faculty at ASU. He previously worked at Sandia National Laboratories as researcher, manager and director of physical and chemical sciences.
