Synopsis
Micro- and Nanotechnology. In modern science and engineering, the borders between existing fields provide some of the best opportunities for research. In my research program I will focus on multidisciplinary, exploratory research in three areas: Non-Traditional Nanofabrication, Self-Assembly-Based Manufacturing, and Nanometer-Scale Charge-Based Printing (NanoXerography).

Non-Traditional Nanofabrication. In my earliest work in this area we concentrated on the development of scanning probe microscopy and scanning probe lithography to study and modify electrical properties on a nanometer scale. Today scanning probe allows fabricating prototypes of devices such as single electron transistors. As a new direction, I suggest a parallel strategy that is 5 orders of magnitude faster. Instead of using a single contact to expose the surface we use a flexible conductive stamp to form multiple contacts of different size and shape.

Self-Assembly-Based Manufacturing. Nature employs self-assembly to create life. Self-assembly to generate materials from atomic, molecular, or super-molecular structures is well-known in materials science, chemistry, and biochemistry. Compared to the extensive studies in these areas, little work has been reported on employing self-assembly on a larger length scale. Our goal is to develop, study, and exploit self-assembly processes as a new manufacturing element in engineering to assemble and package functional hybrid devices in two- and three-dimensions.

Nanometer-Scale Charge-Based Printing (NanoXerography). In xerographic printers, toner particles become trapped in charged areas. In NanoXerography we study the limits of xerographic printing, i.e. fabricate high-resolution charge patterns and investigate their use to organize nanoparticles on surfaces. In the first experiments we achieved a resolution of 2.5 micrometers (20 times the resolution of the best xerographic printer).
