Dennis Hess’s research interests are in thin film science and technology, surface and interface modification and characterization, microelectronics processing and electronic materials. His group focuses on the establishment of fundamental structure-property relationships and their connection to chemical process sequences used in the fabrication of novel films, electronic materials, devices, and nanostructures. Control of the surface properties of materials such as dielectrics, semiconductors, metals, and paper or paper board by film deposition or surface modification allows the design of such surfaces for a variety of applications in microelectronics, packaging, sensors, microfluidics, and separation processes.
