Title: High resolution photoemission studies of the high Tc superconductors
Peter D. Johnson is a Senior Physicist and Chair of the Condensed Matter Physics and Materials Science Department at Brookhaven National Laboratory. He obtained a B.Sc from Imperial College, London in 1972 and a Ph.D from Warwick University in 1978. After a period as a Research Associate at Warwick University working on Photoemission and Photoelectron Diffraction he joined Bell Laboratories in 1981 to work on Inverse Photoemission. In 1983 he joined the Physics Department at Brookhaven National Laboratory and continued the developments of the Inverse Photoemission technique, Spin Polarized Photoemission and more recently High Resolution Photoemission. Significant accomplishments include the first experimental identification of Image States, a new class of surface electronic state, spin polarized quantum well states in thin film and multilayer systems, mass renormalization in the cuprate superconductors, and, recently, a particle-hole asymmetry in the underdoped cuprate superconductors. He introduced new methods of analysis into photoemission including the now widely used Momentum Distribution Curves. Peter was awarded the 2001 Brookhaven Science and Technology Award and the 2011 Oliver E. Buckley Prize of the American Physical Society. He is a Fellow of the American Physical Society, the American Association for the Advancement of Science and the Institute of Physics in the UK.
