Jonathan Harris Orloff is an Americanphysicist, author and professor. Born in New York City, he is the eldest son of Monford Orloff and brother of pianist Carole Orloff and historian Chester Orloff. Orloff is known for his major fields of research in charged particle optics, applications of field emission processes, high-brightness electron and ion sources, focused ion and electron beams and their applications for micromachining, surface analysis and microscopy and instrumentation development for semiconductor device manufacturing.
Career
Orloff received his B.S. in physics from M.I.T. in 1964 and a Ph.D. in applied physics from the Oregon Graduate Center in 1977. Between degrees, he did experimental nuclear physics at the University of Pittsburgh, and worked for a small company beginning in 1970 that was attempting to market a transmission electron microscope with electrostatic lenses. The TEM venture was unsuccessful and abandoned in 1973. The interest Orloff developed in electron optics led him to pursue a Ph.D. at OGC in 1974, under the aegis of Lynwood W. Swanson. From 1978 to 1985 he was an associate professor of applied physics at the Oregon Graduate Center, and a consultant to the Hughes Research Laboratories. He was a full professor in the Department of Applied Physics and Electrical Engineering from 1984 to 1993. In the summer of 1985 he went to France as a visiting scientist by invitation, of CNRS Laboratoire de Microstructures et Microelectronique in Bagneux. During his time at OGC he developed high resolutionfocused ion beam technology, and did optics design for FEI Company, of which he was the fourth partner, and where he also sat on the board of directors. His father Monford Orloff was chairman of FEI until his retirement in 1997. Orloff was a professor at the University of Maryland, College Park in the Department of Electrical and Computer Engineering from 1993 until his retirement in 2006. He has authored or co-authored more than 80 publications, including a Scientific American article and the books Handbook of Charged Particle Optics, of which he is the editor, and High Resolution Focused Ion Beams, with L.W. Swanson and M.W. Utlaut.
Organizational affiliations
Advisory Committee of the Electron, Ion Photon Beam and Nanotechnology Conference, of which he was previously conference chair
