Education

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 career

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 Archived 2019-07-16 at the Wayback Machine , Jinlong Yang and Jianguo Hou, Petek discovered a delocalized electronic structure created by oxygen vacancy on titanium dioxide surface. [9] Together with Jin Zhao Archived 2019-07-16 at the Wayback Machine , 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 Archived 2019-07-16 at the Wayback Machine , 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 Institute for Molecular Science in Japan.
