Welcome to the ARPES Lab at Boston College. It was founded in 1998 by Prof. Hong Ding, from the Department of Physics.

ARPES, or Angle-Resolved Photo Emission Spectroscopy, is a unique experimental tool that analyzes the energy and linear momentum of electrons in a thin (low-dimensional) sample.  This research is used to study strongly correlated electron systems, especially high temperature (or high-Tc) superconductors. ARPES has contributed to understanding the theory behind high-Tc superconductivity by measuring a sample's electronic band structure, Fermi Surface, symmetry of order parameter, pseudo gap, and self-energy, among other variables.

Our on-campus ARPES facility utilizes a helium discharging lamp. See the Equipment page for pictures. We also carry out some of our work in other locations such as:

The Synchrotron Radiation Center in Stoughton, Wisconsin.

The National Synchrotron Light Source in Brookhaven, New York
