Image Theses and Dissertations Quantitative scanning microwave microscopy of a biological cell The electromagnetic properties of a live biological system are extremely important to many medical applications. While information about electromagnetic properties of tissues are available in the literature, little or no data are available for a single cell or subcellular structures. Microwave biological/cell detection has been demonstrated to be useful and promising in many medical applications due to its internal properties such as non-invasive, fast and label-free. View Item

Image Theses and Dissertations Dielectric Spectroscopy of Biological Samples For the first time, the impedance spectrum of live Jurkat T-lymphocytes human cells was characterized in a single sweep spanning six decades of frequency from 9 kHz to 9 GHz. The ultrawide bandwidth bridged the traditional impedance spectroscopy at kilohertz to megahertz frequencies with the recently developed microwave dielectric spectroscopy, which can probe the cell interior without being hindered by the cell membrane.

Image Theses and Dissertations Wafer-scale Fabrication and Characterization of Recessed-channel PtSe2 MOSFETs with Low Contact Resistance and Improved Gate Control For the first time, wafer-scale fabrication of PtSe2 MOSFETs was demonstrated by photolithography. The on PtSe2 is grown by thermally assisted conversion (TAC) of Pt films under Se vapor at 400 °C. Taking advantage of the unique property of PtSe2 to transition from semiconductor to semimetal as its thickness increases beyond a few monolayers, channel recess was adapted for improving gate control while keeping the contact resistance as low as 0.008 Ω∙cm. The wafer-scale fabrication resulted in uniform device characteristics so that average vs. best results were reported, as well as RF vs. View Item

Image Theses and Dissertations Stiffener requirements for plate girders Both the static and fatigue behavior of plate girders are influenced by the stiffeners. Girder strength could be substantially increased by the proper use of stiffners. The objective of this thesis is to review the requirements for stiffeners of welded plate girders. View Item
