Recent years have witnessed a much broader use of Brillouin inelastic light-scattering
spectroscopy for the investigation of phonons and magnons in novel materials …

The design and fabrication of phononic crystals (PnCs) hold the key to control the
propagation of heat and sound at the nanoscale. However, there is a lack of experimental …

Similar to electron waves, the phonon states in semiconductors can undergo changes
induced by external boundaries. However, despite strong scientific and practical importance …

We investigate experimentally and theoretically the acoustic phonon propagation in two-
dimensional phononic crystal membranes. Solid-air and solid-solid phononic crystals were …

We perform a theoretical study based on the transmissions of optical and acoustic waves
normally impinging to a periodic perforated silicon plate when the embedded medium is a …

In this paper, we report on the wave transmission characteristics of a hybrid one dimensional
(1D) medium. The hybrid characteristic is the result of the coupling between a 1D …

We report results of a combined investigation of thermal conductivity and acoustic phonon
spectra in nanoporous alumina membranes with the pore diameter decreasing from D= 180 …

We present a design of a pillared phononic crystal based structure for Love wave
manipulation to achieve high mass sensitivity. The structure is made of phononic micro …

Nanoporous alumina has been extensively used in a wide range of applications, including
template materials for various types of nanomaterials, high surface-area structures for …

Bragg band gaps of phononic crystals generally, but not always, open at Brillouin zone
boundaries. The commonly accepted explanation stems from the empty lattice model …
