On a perfect hydrogen-terminated Si(100)-2x1 surface, each surface silicon atom is capped with exactly one atom of hydrogen. When one of the capping hydrogen atoms is removed, the now unsatisfied orbital of the underlying silicon atom is exposed at that site. This site is better known as a...

Fabrication and characterization of PZT nanorods and nanohexagons with applications in piezoelectric transducers
DownloadFall 2012
All ultrasound devices/sensors use piezoelectric transducers to generate/receive ultrasound. These transducers are made of Pb (Zr0.53Ti0.47) O3 (PZT) materials. In this article, we report a new way of fabricating PZT material with interesting nanorod and nanohexagon shapes. The PZT nanohexagons...

Fundamentals of Film Growth by Glancing Angle Deposition for Inorganic and Inorganic/Liquid Crystal Hybrid Optical Systems
DownloadFall 2011
This thesis investigates two facets of thin film growth via glancing angle deposition. The first half of the work focuses on the fundamentals of film growth with a focus on uniformity and optical design. This portion of the thesis addresses important engineering questions that are relevant to...

High Surface Area Nanoelectromechanical Systems via the Integration of Glancing Angle Deposition Thin Films
DownloadFall 2013
High surface area nanoelectromechanical systems (NEMS) are fabricated using glancing angle deposition (GLAD) thin films as the high surface area layer. The GLAD films are deposited on already-released NEMS cantilevers and doubly clamped beams (DCBs) with good uniformity. The resonance frequencies...
