Single Electron Tunneling at Large Conductance
… First, a diagrammatic expansion in the tunneling conductance is employed to describe the range of weak to moderate tunneling. Then, a formally exact path integral expression is used to determine the linear conductance in the semiclassical regime for various systems. Finally, I performed numerical …

Spectral properties of the random conductance model
… hopping process is the random walk among random conductances where the jump rate between any two sites is the same in both directions. The long-time behavior of such a random walk, when it is killed at the boundary of a large box, is intimately linked to the first eigenvectors and eigenvalues of …

Single Molecule Junction Conductance and Binding Geometry
… effect of binding geometry on single-molecule conductance by varying the structure of the molecules, metal-molecule binding chemistry and by applying sub-nanometer manipulation control to the junction. These experiments are performed both in ambient conditions and in ultra high vacuum (UHV) at …

Electronic structure and quantum conductance of nanostructures
… to study the electronic structure and quantum conductance of realistic nanoscale materials. Electron transport at the nanometer scale involves phenomena which are beyond the realm of classical transport theory: the wave character of the electrons becomes central, and the Schrddinger equation …

Force and Conductance Spectroscopy of Single Molecule Junctions
… statistical evaluation of force and simultaneous conductance data of metallic atomic point contacts and molecular junctions. A conductive atomic force microscope based break junction technique is developed to form single molecular junctions and collect conductance and force data simultaneously. …

Investigation of Melt Electrical Conductance in Food Extrusion
Increase in both the feed rate and the screw speed decreased the mean residence time but the feed rate effect was more pronounced. The specific feeding load, barrel fill and flow profile were affected by the feed rate and the screw speed in opposite directions. Spread of the normalized RTD …

Bipolar Pulse Conductance Measurements With Ion-Selective Electrodes
A novel conductometric approach to monitoring of the calcium and fluoride ion-selective electrodes (ISEs) is presented as an alternative to the classical potentiometric technique. Bipolar pulse conductometric monitoring of ISEs does not require a real reference electrode; two voltage pulses of …

Experimental investigations of solid-solid thermal interface conductance
Understanding thermal interface conductance is important for nanoscale systems where interfaces can play a critical role in heat transport. In this thesis, pump and probe transient thermoreflectance methods are used to measure the thermal interface conductance between solid materials. Two …
