Optically-Assisted Scanning Tunneling Microscopy
… (STM) consistently provides the highest spatial resolution among the scanning probe methods, allowing surfaces to be investigated on the atomic level. With the addition of optical excitation, STM promises to become a powerful technique for single molecule spectroscopy, enabling one to examine the …

Cochlear morphology and sound-induced motion of the apical mammalian inner ear
… motions of cochlear structures with sub-nanometer resolution. This thesis demonstrates the use of the OCT system to study the structure of the inner ears of mice, gerbils, and guinea pigs, as well as the acoustic response of the apical turn of in vitro and in vivo apical mammalian …

DNA translocation through an array of kinked nanopores
… to define synthetic solid-state pores with sub-nanometer resolution. These procedures have in common the formation of nominally cylindrical or conical pores aligned normal to the membrane surface. Here we report the formation of kinked' silica nanopores, using evaporation induced …

Manipulative Scanning Tunneling Microscopy and Molecular Spintronics
… and topographic properties in real-space with sub-nanometer resolution. Still, many physical and chemical effects have yet to be completely characterized and understood. This dissertation demonstrates the novel application of scanning tunneling microscopy to the study of local work functions …

A combined experimental and computational study of nanopaleomagnetic recorders in meteoritic metal
… 3D structure of the cloudy zone was imaged with sub-nanometer resolution using Atom Probe Tomography (APT). This was one of the first applications of APT to image meteoritic metal. Accurate composition measurements of the matrix and tetrataenite as well as kamacite were made. Synchrotron …

X-ray microscope performance enhancement through control architecture change
… known as the Early User Instrument (EUI) was the subject of this work. It consists of X-ray optics stage group that focuses the X-ray beam as a source-size-limited spot onto a sample held on the sample stage group. The controller algorithms that are used should provide the closed-loop with robust …
