Electron Spectroscopy Group
Welcome to the home page for the Electron Spectroscopy Group,
a member of the
Condensed Matter Physics and Materials
Science Department at
Brookhaven National Laboratory on Long
Island, New York. The group employs two main techniques; angle resolved photoemission
spectroscopy (ARPES), and
infrared (IR) spectroscopy. The Electron Spectroscopy Groups primary focus is
on the electronic structure and dynamics of condensed matter systems. The
group carries out studies on a range materials including strongly correlated
systems and thin metallic films. A special emphasis is placed on studies of
high-Tc superconductors and related materials. Some of these experiments are
performed at the National
Synchrotron Light Source. The emphasis is on the study of the
low-energy excitations and the nature of the interactions of the latter with
their environment. The group has also established a successful pulsed laser
deposition facility for the study of thin films. Future plans involve
studies of nanoscale systems and will involve close collaboration and work
within the newly created Center for Functional Nanomaterials.
A brief survey of current research topics include:
-
ARPES and
IR on high-Tc cuprates and iron-based superconductors
-
Charge ("stripe") order in the nickelates
-
Correlated electron systems (intermetallics, etc.)
-
Colossal magneto resistance in the manganates
-
High-dielectric constant materials
-
Quantum magnets
-
Density-functional theory ab-initio calculations of electronic
band structure and lattice dynamics of perovskites
Our experiments are typically performed on
single crystal samples, many of which are
grown and
characterized at Brookhaven.
