Progress and perspectives on phononic crystals [PDF]

Journal of Applied Physics, 2021
Phononic crystals (PnCs) control the transport of sound and heat similar to the control of electric currents by semiconductors and metals or light by photonic crystals. Basic and applied research on PnCs spans the entire phononic spectrum, from seismic waves and audible sound to gigahertz phononics for telecommunications and thermal transport in the ...

Phononic crystals

physica status solidi (b), 2004
Abstract Phononic crystals are periodic composite materials with lattice spacings comparable to the acoustic wavelength. They are of interest not only because of the profound effects of their periodic structure on wave propagation (e.g., the existence of acoustic band gaps), but also because of potential applications (e.g., their ...

Tunable graphene phononic crystal [PDF]

Nano Letters, 2020
Abstract In the field of phononics, periodic patterning controls vibrations and thereby the flow of heat and sound in matter. Bandgaps arising in such phononic crystals realize low-dissipation vibrational modes and enable applications towards mechanical qubits, efficient waveguides, and state-of-the-art sensing.

Tailoring 2D phononic crystal sensor properties by lattice symmerty reduction [PDF]

, 2010
We propose a novel method of tailoring the band structure of 2D phononic crystals (PnC) by reducing the lattice symmetry. Specifically, symmetry reduction by stretching and distorting the crystal face is explored. The transmission spectrum of the PnC was

Hypersonic Phononic Crystals [PDF]

Physical Review Letters, 2005
In this Letter we propose the use of hypersonic phononic crystals to control the emission and propagation of high frequency phonons. We report the fabrication of high quality, single crystalline hypersonic crystals using interference lithography and show that direct measurement of their phononic band structure is possible with Brillouin light ...
