In recent years much effort has been spent on the development of experimental techniques to grow well defined nanoscale materials, due to their possible applications in nanometric electronic devices. Indeed the creation of nanowire field effect transistors [128-132], nano-sensors [133,134], atomic scale light emitting diodes and lasers [135,136], has been made possible by the development of new techniques, which allow one to control the growth processes of nanotubes, nanowires and quantum dots. Of particular importance, among the different atomic scale systems experimentally studied, are... 

Rolf Konenkamp is the Gertrude-Rempfer Professor of Physics at Portland State University in Portland, Oregon. His present research interests lie in the field of nanoscience. He has worked extensively on semiconductor devices, such as nanostructured solar cells and nanowire light-emitting diodes and transistors, and he holds several patents in this area. He has led the design and construction of a new high-resolution photoelectron microscope since 2002. This will be one of the first aberration-corrected microscopes of this type and it will be used to explore transport and confinement effects on the nanoscale. He has worked at NREL, HMI Berlin, Hitachi Tokyo, Princeton University and at the 1ST in Lisbon, and he is a member of the national R D team for thin-fUm photovoltaics in the US. 

CPs have been proven to be excellent materials for optoelectronic applications, e.g. polymer light-emitting diodes and solar cells etc. [106,121]. Numerous smdies have been devoted to this area with the primary focus on thin-film or bulk materials. For CPNWs in particular, recent studies have shown that these materials are very promising candidates for efficient nanoscale photovoltaic devices [30,52,54,57]. Figure 10.53 shows the optical response of a single CPNW in terms of photocurrent towards light exposure [52]. 

Poly(phenylenevinylene) has been considered for many different applications due to its importance in nanoscale electronic devices. One such application is the search for efficient light emitting diodes. This property is the result of the electrooptical effect and constitutes an important area of modern research in theory as well as experiment. The efficiency of the nonradiative... 

The self-assemble morphologies with nanoscale architectures in thin film of conjugated block copolymer are of current interest for device application, such as light-emitting diodes.
