RESEARCH ACTIVITIES

Richard Kiehl explores device concepts, self-assembly techniques and circuit architectures for nanometer-scale electronics for information processing, signal processing, and sensing applications. A theme in his research is the exploration of novel concepts at the interface between electronics and biology. This includes work on nanoscale circuitry based on radically different approach for information processing in which the electrical phase of a dynamical process is used to represent logic states in an ultrasmall device. He also investigates device concepts for nanoscale circuitry based on Coulomb blockade in nanoparticles and nonlinear behavior in organic molecules. These studies include nanotube and nanowire FET's, which utilize novel e-beam lithography and scanning probe techniques for fabrication and characterization. Metal-molecule-metal junctions exhibiting negative differential resistance are also of interest because of their potential for realizing self-assembled circuitry at the single molecule level. An example of his research at the interface between electronics and biological systems is the use of DNA as a scaffolding for self-assembling nanoparticles, nanowires, and molecules into electronic circuitry. This approach promises the integration of devices at densities far beyond those possible with lithographic techniques. His work also includes collaborative studies of the electronic properties of nanoparticle arrays self-assembled by DNA, peptides and protein structures. While his work is primarily aimed at information processing applications, he is also interested in exploiting the unique characteristics of nanoscale devices (e.g., sub-electron charge sensitivity in single electron transistors and magnetic & plasmonic interactions in nanoparticle arrays) for biomolecular sensing and imaging applications.
