Petek received his B.S. degree in chemistry from Massachusetts Institute of Technology in 1980.[3] Subsequently, he obtained his Ph.D. degree in chemistry from the University of California, Berkeley in 1985.[4]

Research and careerEdit

Petek has developed coherent photoelectron spectroscopy[5][6] and microscopy[7] as methods for studying the dephasing and spatial propagation of polarization fields in solid state materials and nanostructure. He is developing methods for multidimensional multiphoton-photoemission spectroscopy.[8] Together with Taketoshi Minato, Yousoo Kim, Maki Kawai, Jin Zhao, Jinlong Yang and Jianguo Hou, Petek discovered a delocalized electronic structure created by oxygen vacancy on titanium dioxide surface.[9] Together with Jin Zhao, Ken Jordan and Ken Onda, Petek also discovered wet electron states, where electrons are partially solvated by water and other protic solvents at molecule vacuum interfaces.[10] Together with Min Feng and Jin Zhao, Petek discovered atom-like superatom states of C60, and similar hollow molecules.[11] Petek's research of metal plasmon excitations with semiconductor substrates, unrevealed the charge injection from optically active plasmonic modes into semiconductor substrates.[12]

Petek is Editor-in-Chief of Progress in Surface Science[13] and has organized conferences such as the 11th International Symposium of Ultrafast Surface Dynamics, held in Qiandao Lake, China.[14] Petek has been (2015-2019) a member of the National Research and Development Agency Committee for the National Institute for Materials Science and is currently a senior scientific advisor to the Japanese Institute for Molecular Science.[15]
