1. Nanotechnology for Aerospace Research: Surface Science Applications

   29 Mar 2016 | Online Presentations | Contributor(s): Dmitry Zemlyanov

   Surface Analysis Facility at Birck Nanotechnology Center, Purdue University, equipped with state-of-art analytical equipment, which can greatly benefit many researchers from Schools of Engineering and College of Science. I would like to demonstrate examples of the studies using X-ray photoelectron spectroscopy (XPS), scanning tunneling microscopy/spectroscopy (STM), high–resolution electron energy loss spectroscopy (HREELS), low energy electron diffraction (LEED).

2. XPS Thickness Solver

5. Surface Characterization Studies of Carbon Materials: SS-DNA, SWCNT, Graphene, HOPG

   16 Feb 2010 | Online Presentations | Contributor(s): Dmitry Zemlyanov

   In this presentation examples of surface characterization studies of carbon specimens will be presented. (1) In particularly, the systematic XPS (X-ray photoelectron spectroscopy) characterization of graphene grown on the SiC surface will be reported. This work demonstrates a use for XPS to characterized surfaces, providing critical information on thickness of graphene layers. XPS data will be compared with the Raman data. (2) Covalent Cross-linking Between polythymidine DNA and Single-walled Carbon Nanotubes (SWCNT) will be considered. The interaction of ss-DNA with SWCNT and Highly Ordered Pyrolytic Graphite (HOPG) will be compared. (3) Modification of HOPG surface with mild AC plasma (O2, H2, Ar, H2O) will be discussed.
