Peter Johnson (physicist)

Peter D. Johnson (born January 30, 1952 in Wellingborough , England ) is a British solid-state physicist.

Johnson graduated from Imperial College London with a bachelor's degree in 1972 and received his PhD from the University of Warwick in 1978 . At that time he was working on photoemission and diffraction of photoelectrons. From 1981 he was at Bell Laboratories where he worked on the inverse photo effect . From 1983 he was at Brookhaven National Laboratory , where he became a senior physicist and head of the solid state physics and materials science department.

At Brookhaven National Laboratory he continued his work on methods that use the inverse photoelectric effect, spin-polarized photoemission and high-resolution photoemission. He used it to research the spin-resolved structure of solid surfaces, thin films and multilayers. In doing so, he discovered new types of electronic surface states (image states), spin-polarized quantum well states, mass renormalization in high-temperature copper superconductors and a particle-hole asymmetry in high-temperature copper superconductors doped with holes. He developed new methods of photoemission spectroscopy such as momentum distribution curves .

In 2011, together with Juan Carlos Campuzano and Zhi-Xun Shen, he received the Oliver E. Buckley Condensed Matter Prize for innovations in angle-resolved photoemission spectroscopy that advanced the understanding of high-temperature superconductors and transformed the study of highly correlated electronic solid-state systems (laudation). He is a Fellow of the American Physical Society , the Institute of Physics, and the American Association for the Advancement of Science . In 2001 he received the Brookhaven Science and Technology Award.
