Abstract: The Sandia National Laboratories' (SNL) Physical, Chemical, and Nano Sciences Center in Albuquerque, NM provides new scientific knowledge in support of Sandia's national security mission. The Center is Sandia's leading performer of focused long-term scientific research in anticipation of future national security needs, particularly in the physical, chemical, and nano sciences, focused on five technical thrusts: science-based solutions for enduring NNSA mission needs, collective hierarchical systems, compound semiconductor science and technology, nano sciences, and optical sciences. I will provide a brief overview of highlights of select activities in the Center (i.e., remote optical sensing and ultra-wide band gap materials), with a focus on some of the activities of the Nanoscale Sciences Department. More specifically, I will describe highlights associated with Sandia’s recent graphene device research activities, and the innovative use of surface and laser-based characterization (i.e., Spectroscopic Raman imaging and spectroscopy) for assessing the electronic and thermal properties of these devices and materials.

*Sandia is a multiprogram laboratory operated by Sandia Corporation, a Lockheed Martin Company, for the U.S. DOE’s National Nuclear Security Administration under Contract No. DE-AC04-94AL85000. CINT is one of five nanoscience research centers across the United States funded by the DOE Office of Basic Energy Sciences.

Bio: Carlos Gutierrez received his Ph.D. and M.S. Degrees in Physics and Astronomy from the Johns Hopkins University, and a B.S. in Physics from the University of Dallas. After graduate school, he served as a National Research Council Postdoctoral Research Associate at the Naval Research Lab conducting spintronics research. Prior to joining Sandia, Gutierrez was a Professor of Physics at Texas State University from 1992-2005, where he became the university’s first NSF Early Career recipient from the Division of Materials Research. Gutierrez’ Nanoscale Sciences Department at Sandia National Labs conducts interdisciplinary materials research at the nanoscale regime aligned along four research thrusts: (1) advancing materials & device understanding enabled by innovative surface and interface metrology; (2) the development of nanoporous and nanostructured materials for various applications; (3) advancing the understanding and application of low dimensional materials (i.e., carbon nanotubes, graphene, nanofibers, quantum dots); and (4) advancing the understanding of the thermal science of materials at the nanoscale (i.e., for thermal management, thermoelectrics). He is providing Science and Technology management leadership to emerging programs in graphene and 2D materials, and to materials business development activities related to nanoporous materials (including metal-organic frameworks), thermal interface and thermoelectric materials, hazardous waste form capture materials, and magnetic materials.
