Research

Professor Hipps completed his Ph.D. in Chemical Physics at WSU in 1978. He joined the faculty at WSU in 1979 following his tenure as a National Science Foundation energy-related postdoctoral fellow at The University of Michigan. He has received several honors such as being chosen a Fellow of the Alfred P. Sloan Foundation, receiving the Washington State Teachers Association, “Teacher of the Year,” Award, the WSU Distinguished Faculty Award, the Graduate and Professional Students Outstanding Advisor Award, and the Phi Lambda Upsilon local chapter Distinguished Faculty Award. His STM images have graced the covers of six editions of prestigious ACS journals including the Journal of Physical Chemistry, Langmuir, and the Journal of the American Chemical Society. He is also currently a Fellow of the American Chemical Society, a Fellow of the American Physical Society, and a Fellow of the American Association for the Advancement of Science, and a Fellow of the American Vacuum Society. He is also a member of the Washington State Academy of Sciences.

Much of the exciting physics and chemistry of modern technology occurs not in the body of materials, but rather at the interface between materials. For example, the catalytic converter in every modern automobile reduces harmful emissions by promoting reactions at the solid-gas interface. Modern electronic devices function only because of the variation in potential and composition that occurs over a few nanometers at the boundary between different solids. Thus, the study of surfaces and interfaces is of critical importance to physical science, medical science and to technological development.Also of great current interest (for both science and technology) are processes and materials on the nanometer scale. This area of research is often called nanotechnology. Nanotechnology spans chemical preparation, structure determination, electronic, optical, and mechanical property measurements.

In our laboratories we study the basic chemical and physical processes and structures which occur on surfaces, in interfaces, and that relate to nanoparticles. Scanning Tunneling Microscopy, Scanning Force Microscopy, Transmission Electron Microscopy, Tunneling Spectroscopy, X-ray Photoelectron, UV Photoelectron, Raman, Infrared, and EPR spectroscopy are all used to probe the world on a scale of nanometers.  Work in our laboratory spans the disciplines of chemistry, physics,materials science, and nanotechnology.

A graduate student might undertake one of several projects. The extension of scanning tunneling microscopy-spectroscopy to variable temperatures and pressures to study chemical processes at the single molecule level has high priority. In this project, we are probing molecular structure, kinetics, and thermodynamics based on measurements made at the single molecule level. We are also deeply involved in measuring electron transfer processes at the sub-molecular scale. How do different parts of molecules transmit electrons? Thin film structure and reaction chemistry problems as they relate to sensors are of intense current interest in our group. Organic nanostructures formed my ionic self-assembly are being studied at the nanometer scale to unravel the connections between structure and mechanical and electronic properties. For the theoretically-inclined student, we have a number of both fundamental and computational problems that require solutions.

Typical skills learned by my students include X-ray and electron spectoscopy, vibrational spectroscopy; electron tunneling spectroscopy;  optical, electron, and scanning probe microscopy; materials characterization techniques; computer programming and interfacing; thin film processing; high and ultra-high vacuum technology; and cryogenic techniques. Many students design and build, or have built, instruments required to advance their research. These individuals also acquire a good working knowledge of electronics, machining, and CAD.
