Surface‐enhanced infrared absorption (SEIRA) has attracted increasing attention due to the
potential of infrared spectroscopy in applications such as molecular trace sensing of solids …

Plasmonics is a rapidly growing field spanning research and applications across chemistry,
physics, optics, energy harvesting, and medicine. Ultrafast photoemission electron …

We present a micro-Raman study of InP/InGaP tandem junction photovoltaic nanowires.
These nanowires render possible InGaP compositions that cannot be made in thin films due …

We report on the intrinsic optical generation and detection of coherent acoustic phonons at
(001)-oriented bulk Si and GaP without metallic phonon transducer structures …

The Berreman effect, by which thin films of polar dielectric materials exhibit strong, narrow
resonances near their longitudinal optic (LO) phonon frequency, results in strong material …

We demonstrate an all-optical approach to probe electronic band structure at buried
interfaces involving polar semiconductors. Femtosecond optical pulses excite coherent …

A theoretical model has been developed for determining the free electron concentration in n-
InAs specimens from characteristic points in far IR reflection spectra. We show that this …

We experimentally study the effect of amplitude-varying surface acoustic waves on a
localized surface plasmon (LSP), which unveils exceptional properties of plasmon-phonon …

A theoretical model has been developed for determining free electron concentration in n-
GaAs from characteristic points in the far infrared region of reflection spectra. We show that …

We report on the optical generation and detection of ultrashort acoustic pulses that
propagate in three-dimensional semiconductor crystals. Photoexcitation of lattice-matched …
