Mr. Zacharias George

The primary focus of my research is to design and fabricate Atomic Force Microscope probes that operate at high AC frequencies. The fabrication of this custom probe will enable gigahertz excitation and measurements of nanometer-sized devices. Further, this would allow for the characterization of magnetic tunnel junctions, and possibly phase change devices, both of which are currently being investigated here at Carnegie Mellon University.
