The Physics Department Spring 2012 Seminar Series is proud to welcome Katherine Aidala, Clare Boothe Luce Assistant Prof. of Physics, Mt. Holyoke College, for a talk entitled: Atomic Force Microscopy: A Versatile Tool in Nanoscale Science
The atomic force microscope (AFM) brings a small (about ten nanometer) tip close to or into contact with a surface. Anything that causes the tip to move up and down can be measured, whether it's the surface directly deflecting the tip as it passes over a bump, or a charge on the surface creating a force on the charged tip just above. I will discuss the many ways the AFM is used in nanoscale science, drawing examples from my research lab. By attaching bacteria to the tip, we can measure the adhesive forces between bacteria and different surfaces. We can pass current through the tip to create a magnetic field to manipulate magnetic states in ferromagnetic nanorings, with possible applications in data storage. Nanocrystal quantum dots have promising optical and electronic properties to be used in LEDs and solar cells, and the AFM allows us to understand the topography and electrical properties of arrays of these dots.
Pizza and Refreshments will be available for $1. Please bring your own cup. Remember to Recycle, Reuse, Reduce.
