Optical diagnostics of thin films Assembly of nanocrystals Irving Philip Herman (born 1951) is an American physicist and the Edwin Howard Armstrong Professor of Applied Physics at Columbia University.
[2][3] Herman has advanced several fundamental aspects and applications of laser interactions with matter, optical diagnostics of thin film processing, including by real-time monitoring, and nanoscience, along with cited (excellent) collaborators.
These and his related studies have improved understanding and control of the assembly and processing of materials for semiconductor and optical devices, and the properties of these thin films, nanomaterials and nanocomponents, such as colloidal nanocrystals.
[16][27][28] His studies of semiconductor and nanomaterial structures at high pressure used optical diagnostics to probe changes in epilayer strain and nanocrystal interactions in films.
[16][27][28] Earlier, he achieved ultrahigh single-step selectivity in the laser isotope separation of deuterium and tritium, to help the production and cleaning of heavy water for fission reactors.
