  • Ph.D. 1962 University of Missouri

Interests:

Professor Lapeyre's research in the solid state and surface science laboratory focuses on the electronic states and electron interactions in solids and at surfaces. A strong emphasis is placed on quantum properties of MBE grown III-V semiconductor surfaces. The principal spectroscopies used are polarization dependent angle-resolved photoemission spectroscopy (PARUPS) in the far and extreme ultraviolet spectral range and high resolution low energy electron loss spectroscopy (HREELS). LEED, ESCA, and Auger are used for multiple sample analysis. Two sources of photon flux are available. In the Montana State University laboratory, gas discharge lamps and x-rays are used. The MSU lab group is also a user group at the Synchrotron Radiation Center at the University of Wisconsin, where the group has its own beam line which covers the spectral range from about 5 to 1000 eV.
