Fall 2010
This thesis describes the fabrication and characterization of integrated hollow Bragg waveguides fabricated by controlled thin film buckling. Hollow waveguides based on two different set of materials were studied. In the first case, thermal tuning of air-core dimensions was studied using...

Miniaturization of Microwave to Millimeter-Wave Integrated Waveguides and their Applications
DownloadFall 2019
The integration of waveguide technology at the planar level has been a crucial development for the successful realization of 5G, the future fifth generation cellular network. The demand for mobile networks with faster speeds, lower latencies, and denser connectivity scenarios continues to drive...

Observing and Manipulating Single Electrons Confined to Silicon Dangling Bond Ensembles with Non-Contact Atomic Force Microscopy
DownloadFall 2018
Non-contact atomic force microscopy (nc-AFM) is capable of inducing and resolving single-electron charge transitions of surface adsorbates. Here, these techniques are extended by studying the charge configurations of dangling bond (DB) ensembles on the hydrogen-terminated silicon surface. nc-AFM...

Spring 2014
The impressive developments in the semiconductor industry over the past five decades have largely been dependent on the ability to continually reduce the dimensions of devices on a chip. However, as critical dimension requirements for these devices approach the limits of photolithography, new...

Fall 2014
This thesis is focused on the Si-based anode materials for lithium-ion batteries (LIBs) as well as biomass-derived carbons for LIBs and sodium-ion batteries (NIBs). In our first attempt we investigated the effect of the support growth substrate as well as of aluminum coating layers on the...

Spring 2015
This thesis is focused on the silicon-based anode materials for lithium-ion batteries (LIBs) as well as germanium-based electrode materials for sodium-ion batteries (NIBs). In our first attempt we studied electrochemical cycling stability and degradation mechanisms of silicon nanowires (SiNWs)...

Spring 2017
We present the characterization of close-spaced linear dangling bond structures, or dangling bond chains, two to seven dangling bonds long, on a hydrogen terminated silicon (100)-2x1 surface using a scan- ning tunnelling microscope. Constant height differential conductance maps reveal their local...

Dangling Bonds (DBs) on the silicon surface exist when a silicon atom lacks a bonding partner, resulting in a localized orbital which is not involved in any chemical bonds. On the hydrogen-terminated Si(100) surface, such DBs introduce a mid-gap state. DBs can be created on this surface by the...
