Earl Ward Plummer (October 30, 1940 – July 23, 2020) was an American physicist. His main contributions were in surface physics of metals. Plummer was a professor of physics at Louisiana State University, University of Pennsylvania and the University of Tennessee - Knoxville. Biography Plummer received a Bachelor of Arts degree from Lewis & Clark College in 1962 and completed his Ph.D. degree in physics at Cornell University in 1967, working with Prof. Thor Rhodin. His thesis work was on atomic binding of 5-d transition-metal atoms using Field ion microscope (FIM). Plummer accepted a National Research Council Postdoctoral Fellowship at the National Bureau of Standards (now called The National Institute of Standards and Technology (NIST)) in the fall of 1967 working with Russ Young, and he stayed as a staff scientist until the fall of 1973. His work included field electron emission and photoemission studies of surfaces. NIST selected his 1969 paper "Resonance Tunne ...
