The goal of this program is to develop and combine novel and conventional processing techniques and materials to create functionally enhanced devices for flexible large-area electronics. The proposal consists of the design and fabrication of new structures based on hybrid nanowire/thin-film devices, implementing novel solution processing techniques for nanowire assembly, enhancing device integration and performance using pulsed-laser processing, and demonstrating a prototype integrated system. The major areas of research will be: 1) silicon nanwire (SiNW) synthesis using chemical-vapor deposition (CVD) and plasma-enhanced CVD techniques for low-temperature nanowire growth on plastic substrates and in-situ fabrication of hybrid nanowire/thin-film device structures, 2) development of SiNWs suspended in liquid for solution-based processing 3) maskless non-contact patterning, assembly, and testing of SiNW devices using jet-printing processes, 4) design and fabrication of novel doping profiles for electrical contacts and junctions by pulsed-laser processing, and 5) design, fabrication, and testing of SiNW-based solar cells and batteries using hybrid amorphous Si/SiNW device structures on plastic. The outcome of this research will result in functionally enhanced large-area electronic systems that will impact the display and medical imaging industry with long-term influence on emerging applications for e-readers and e-paper. Each of the research components can also be used for a variety of applications, permitting easy dissemination of technology to industry. The range of technical areas will educate and train UW students in the field of nanotechnology, preparing them to lead the development of the next generation of large-area flexible nanoelectronics.
