SXSS Group - Infrared Spectroscopy

Microscope

 

Welcome to the unofficial web site for the Infrared component of the soft x-ray scattering and spectroscopy (SXSS) group within the National Synchrotron Light Source II at Brookhaven National Laboratory on Long Island, New York.  This site will focus on the capabilities of the MET and future INF infrared beamlines at the NSLS II.  In addition, collaborative research is also carried out on a variety of materials, including strongly correlated electron systems, with particular attention to emergent phenomena, such as superconductivity.  A brief survey of techniques and topics include:

  • Infrared microscopy

  • Scanning near-field optical microscopy (SNOM)

  • Reflectivity and ellipsometry

  • High-Tc cuprates and iron-based superconductors

  • Topological insulators; Dirac and Weyl semimetals

  • Correlated electron systems (intermetallics, etc.)

  • Density-functional theory ab-initio calculations of electronic band structure and lattice dynamics of perovskites and related materials

In order to carry out these studies instrumentation will be developed for optical reflectance and transmission studies featuring lab-based as well as synchrotron light sources. Some of the samples examined are grown and characterized at Brookhaven.  

 

This site previously hosted the web page for the Electron Spectroscopy Group in the Condensed Matter Physics & Materials Science Department, which was defunded in 2021.  The old web site may be found at:

One of ten national laboratories overseen and primarily funded by the Office of Science of the U.S. Department of Energy (DOE), Brookhaven National Laboratory conducts research in the physical, biomedical, and environmental sciences, as well as in energy technologies and national security. Brookhaven Lab also builds and operates major scientific facilities available to university, industry and government researchers. Brookhaven is operated and managed for DOE's Office of Science by Brookhaven Science Associates, a limited-liability company founded by Stony Brook University, the largest academic user of Laboratory facilities, and Battelle, a nonprofit, applied science and technology organization.
