Charles M. Falco (born August 17, 1948) is an American experimental physicist and an expert on the magnetic and optical properties of thin film materials.
Falco earned his Ph.D. at the University of California, Irvine in 1974 and spent the next eight years at Argonne National Laboratory before joining the University of Arizona in 1982 as a Professor of Optical Sciences. In 1989, he received the Alexander von Humboldt Foundation Senior Distinguished U.S. Scientist Award, and in 1998 was awarded the UA Chair of Condensed Matter Physics. Falco, a Fellow of the American Physical Society, the Institute of Electrical and Electronics Engineers (IEEE), the Optical Society of America, and the Society of Photo-optical Instrumentation Engineers (SPIE) has published more than 250 scientific manuscripts, most of which are related to physical properties of materials produced by Molecular Beam Epitaxy (MBE), co-edited two books, has seven U.S. patents, and has given more than 250 invited talks on his research at conferences and research institutions in 25 countries.
