Masashi Yamaguchi
Assistant Professor of Physics
Education
B.S., Applied Physics, Hokkaido University, 1986
M.S., Applied Physics, Hokkaido University, 1988
Ph.D., Applied Physics, Hokkaido University, 1991
Career Highlights:
Yamaguchi’s accomplishments include the fundamental understanding of structural
evolution in partially ordered crystals, glasses, and supercooled liquids using
time-domain and frequency domain spectroscopy. Specific examples are discovery of
a new acoustic anomaly in the phase transition of quantum parelectric crystals
(the dielectric constant increases when the temperature decreases); measurements
of elastic stiffness of MOCVD (Metal Organic Chemical Vapor Deposition) grown lattice
mismatched nitride semiconductors; manipulation of acoustic phonons using impulsive
stimulated Brillouin light scattering; polariton based THz spectroscopy for study of
large-scale fluctuations of ferroelectric nanodomains and the THz acoustic spectroscopy
for the study of elastic modulus constant of amorphous thin films.
Research Areas:
Structural and electronic dynamics in condensed matter, THz spectroscopy of
advanced materials and THz science and technology.
