Nanomanufacturing

Over the past two decades, nanoscience and technology has been extensively researched due to novel material properties, and potential for improvement of a variety of products in the electronics, photonics, energy-conversion, and biology fields.  The initial phase of new material synthesis methods was followed by a second phase of demonstrating potential applications and uses for these materials.  In the third phase, a major challenge is the development of new manufacturing processes to facilitate the transition of these technologies from the laboratory to the marketplace.  This will require the development of scalable, low-cost manufacturing processes capable of synthesizing high quality materials with high throughput over large areas. Additionally, quality control on a manufacturing scale will require novel metrology tools capable of characterizing large quantities of nanomaterials in situ with high spatial and temporal precision.  We have developed a variety of nanomanufacturing machines and processes, with an emphasis on low energy and raw material inputs, without the need for cleanroom processes such as photolithography, which can be substituted by scaleable technologies such as self-assembly or transfer processes.  We also emphasize use of low-cost, flexible substrates compatible with processes such as roll-to-roll manufacturing, which has been identified as a key technology for reducing the cost of solar cells and other energy devices.
