    RET 2010 Symposium Presentation
    Here is my presentation on the characterization of graphene using kelvin probe microscopy that I will present on July 30th, 2010 at the RET symposium at the University of Notre Dame.

    RET 2009
    This summer kicks off my second year in the RET program at Notre Dame. I will again be working with Dr. Xing in the Electrical Engineering department. My focus is quite similar, as I am still focusing on the creation of a functional nano-scale pH meter. However, there has been a material change. Last summer I was working with GaAs as a semiconducting material; whereas this summer, I will work on depositing (via a variety of methods) a thin sheet of graphene onto either silicon/silicon dioxide and/or copper foil. Graphene is especially exciting because it is theoretically a more energy efficient and "faster" material from which to build transistors. Silicon tends to hit a speed barrier around 10 nm, whereas graphene does not see this limitation.

    Presentation on work to Graphene group on campus at Notre Dame, July 19th, 2010:
    CVD Grown Graphene Characterization via AFM & SKPM on Prezi
    Since I have begun participating in RET, I have learned how to use the following equipment/techniques used to characterize solid state electronic devices:
    Veeco Nanoscope IV for Atomic Force and Kelvin Probe Microscopy
    Hall Effect Measurements
    Keithley Semiconductor Parameter Analyzer
    Digital Camera Probestation
    CVD Furnace for graphene growths on copper substrates
    Silicon cleaning procedures
    Hitachi Scanning Electron Microscope

    RET 2010
    I am now entering my third summer at Notre Dame working with Dr. Grace Xing in the Electrical Engineering department. I will continue my work with graphene, and will refine my AFM skills, as well as learn a new AFM technique: Scanning Kelvin Probe Microscopy .

    The report was just finished yesterday, so it is still somewhat raw. You can see the final report here:

    Next I will be working with solar cell technology, testing the efficiency of solar cells at different wavelengths and intensity of light. The experiment involves shining a laser beam on a solar cell. I have done initial data collection with solar cells. I have taken the current generated, along with the power of the laser beam at different wavelengths.

    My first results from the solar cell experiment are here:
