Dr. Ishigami received his Ph.D. in Physics from the University of California, Berkeley in 2004. He has been on the faculty at UCF since 2008.
I am an expert on scanning tunneling microscopy and spectroscopy, transport measurements on nanoscale materials, and nanoscale friction measurements at speeds reaching 1 m/sec. Using these techniques, I study
- The impact of atomic scale defects and adsorbates on transport properties in novel 2D materials with exotic electronic structures.
- The transport properties of chiral-angle known nanotubes (particularly, how individual atoms and molecules affect the device properties)
- The origin of friction and wear
Results are useful to develop a broad scientific foundation for nanotechnology including novel electronic, sensor and friction-reduction technologies.
