Irving P. Herman
Department of Applied Physics and Applied Mathematics (APAM)
Professor (Optical and Solid State Physics, and Materials Science)
Member, Columbia Nanoinitiative
S.B., Massachusetts Institute of Technology, 1972
Ph.D., 1977
Biography:
IRVING HERMAN graduated with S.B. and Ph.D. degrees in physics from
M.I.T. in 1972 and 1977. From 1977-1986 he was a member and section
leader in O-group within the Physics Department at the Lawrence
Livermore National Laboratory, where he was engaged in research in
laser isotope separation of deuterium and tritium, and the use of
direct laser writing in thin film processing. In 1986, he joined the
faculty of Columbia University, where he is now Edwin Howard Armstrong Professor of Applied
Physics. From 2006-2012 he was chair of the Department of Applied
Physics and Applied Mathematics, and became chair again from 2018-2021. From 1998-2010 he was
Director of the Columbia Materials Research Science and
Engineering Center (MRSEC) [The Center for Nanostructured Materials], and as part of this he led an
extensive education outreach program. He was Director of the Columbia Optics and Quantum Electronics IGERT (Integrative Graduate Education and Research Traineeship program) from 2015-2019. He has overseen the Shared Materials Characterization Laboratory and was a member of the CNI Facilities Committee. He was a member of the Columbia Nanoinitiative (CNI) and the Columbia Materials Research Science and
Engineering Center (MRSEC). He is a fellow of the American
Physical Society and the Optical Society of America (now Optica).
His career at Columbia University has been one of diverse scholarly activities.
His research activities have included the use of lasers to induce reactions at surfaces and for surface analysis,
Raman microprobe spectroscopy, and topics in nanoscience and optics,
including the assembly and analysis of nanocrystals and, more recently, van der Waals layers.
In addition, he has written three books: a comprehensive monograph on optical diagnostics for thin film processing,
a comprehensive textbook on physics of the human body, which is now in its second edition, and a semipopular book that tries to get adults to love math.
He has developed three interactive seminars on ethics and presents them to students in his department,
and has published on this subject. He has also examined the interwoven history of the
Columbia University School of Engineering and Applied Science and events in New York City.

Research Interests:
His research concentrates on the fundamental aspects and
applications of
laser interactions with matter and nanoscience. This includes
properties of nanocrystals and films composed of nanocrystals, van der Waals layers, optical
physics of the solid
state, molecular and chemical physics, thin film processing, and
optical
spectroscopy.
One active area of research in his group is the study of the
optical properties of semiconductor and metal oxide nanocrystals and how to assemble them into films by
controlled evaporation and electrophoretic deposition (electric field directed assembly).
He is also interested in van der Waals layers, including how
to interface them with nanocrystals. His research includes Raman analysis of these
nanocrystal and van der Waals layer assemblies, and understanding how they can be interesting components of
device structures.
Another active area of research in his group is the use of optical spectroscopies
to probe the physical and chemical events that occur in the thin film processing
of microelectronic materials. These techniques are also called real-time
optical diagnostics. He has used laser desorption and laser-induced fluorescence
spectroscopies to probe the adlayers at the surface during novel types
of plasma etching. These optical diagnostic studies also address the use
of optical microprobe methods with tightly focused lasers to analyze patterned
processes with high spatial resolution.
He is also interested in optical spectroscopy of semiconductors,
and
in particular in the effects of strain, confinement and temperature on
these materials. He has studied phonons in materials
like germanium-silicon alloys by Raman microprobe spectroscopy. He has
also studied the optical spectroscopy of materials subjected to high
pressure in
diamond anvil cells, including thin films, multiple-quantum
wells, and nanocrystals of novel light-emitting IV, III-V, and II-VI
semiconductors by using photoluminescence and other optical methods.
The goal
of these studies was to understand the properties of electronic and
optoelectronic
materials better, in order to make more efficient use of them in
applications
and design of even better structures.
His research has also been in related areas of optical physics,
including studies of optically pumped lasers, laser isotope separation,
infrared laser multiple-photon dissociation, laser chemical modifications
of surfaces, and optical microanalysis of semiconductors.
He has also developed a first year/second year undergraduate course on "Physics of the Human Body",
has published the textbook
"Physics of the Human Body"
(Springer, Berlin-Heidelberg-New York, 2007) for this course, which has been translated from Brooklynese
into Japanese and Greek, and a second edition in 2016,
and has published the
monograph
"Optical Diagnostics for Thin Film Processing"
(Academic Press, San Diego, 1996). He has published review articles on
optical diagnostics,
Raman scattering,
optical thermometry,
laser-assisted deposition,
laser separation of tritium,
direct laser writing, and
laser isotope separation.
He recently published the semipopular math book
"Coming Home to Math: Become Comfortable with the Numbers that Rule Your Life" (World Scientific, 2020).
