Dr. Aaron Tynes Hammack is a Postdoctoral Fellow in the Imagining Division facility of the Molecular Foundry at LBNL. Dr. Hammack received his Ph.D. in 2010 from the University of California at San Diego in Condensed Matter Physics. He was a member of the experimental team responsible for the creation of the first electro-optical and all-optical excitonic tranisitors as well as the first direct measurements of spatial coherence in quantum degenerate exciton gases. During his undergraduate work at UC Berkeley, he worked on the characterization of indium and gallium self assembled nano wires on the silicon surface by scanning tunneling microscopy and spectroscopy. For the past two years he has worked on the Nano Surfaces Molecular Foundry Challenge Grant to characterize the effects of nano particle size and surface binding environments on their emergent properties through XPS, XAS, XES, Auger, and scanning probe characterization techniques. Dr. Hammack is an expert in materials characterization techniques ranging from far field optical characterization to x-ray spectroscopy, scanning electron microscopy, scan probe microscopy, and Auger electron spectroscopy. He is also an expert in device fabrication through photo and e-beam lithography as well as numerical programming for complex data analysis and physical modeling. Dr. Hammack has co-authored 21 publications in peer reviewed journals on topics focused on the spectroscopic characterization of electronic, magnetic, and optical properties across a wide range of inorganic and hybrid organic/inorganic materials systems.
