Essay

In order to continue the ever impressive and successful scaling pace of MOSFETs, tremendous research efforts have been devoted to the search of new materials to complement or replace Si as the Si-based ones are predicted to reach theoretical limits soon. Ge has low band gaps and high carrier mobilities, thus offering appealing potentials as a candidate of choice for future electronics. For the same purpose of discovering new materials, another area of interest is low dimensional nanostructures such as nanowires (NWs), owing to the facile synthesis, high structure perfection and superior properties. In this context, Ge NW has combined advantages and is particularly promising. My thesis focuses on this subject and has advanced in a wide range, from understanding and controlling synthesis and surface chemistry, to highly ordered assembly and devices with excellent performance...[more; pdf file - 321KB]
