The process is a sharp departure from conventional nanolithographic techniques in both method and amount of time required. Epitaxial graphene prepared on single crystal 4H-SiC was etched with O2 plasma through 0.2 ìm porous filters adhered to the surface of the sample. Thickness measurements using ellipsometry and topological mappings using atomic force microscopy were conducted to ascertain the extent of graphene nanoribbon formation. Sheet resistance of the samples was measured using the four-point van der Pauw method to ensure the existence of electrical conductivity in the etched samples. Furthermore, the etch-rate of multilayer epitaxial graphene was determined. http://smartech.gatech.edu/handle/1853/28711 Title: The Effect of Cross-Linker Densities on Shape-Memory Polymer Composites: Optimizing and Utilizing Component Materials for Orthopedic Casts <br/> <br/>Authors: Norred, Liz <br/> <br/>Description: Presented at the 4th Annual Undergraduate Research Spring Symposium, April 1, 2009 in Room 321 of the Georgia Tech Student Center.
