Porous Silicon Phononic Crystals

Research output: Chapter in Book/Report/Conference proceedingChapter

Abstract

Work on phononic crystals in porous silicon is first put in context of the more
general interest in controlling wave behavior in periodic media in both photonic
and phononic crystals. The condition for a stop band for acoustic waves is
derived by analogy with the Bragg condition with optical multilayers and then
also obtained from the Rytov theory of layered acoustic media. The modeled
acoustic bandgap in porous silicon is then defined and examined with the
parameters used to model acoustic velocities in the material. A historical overview
of papers covering theory and experiments on acoustic bandgaps in porous
silicon is then given with an emphasis on their hypersonic nature and phoxonic
properties. Finally, applications of acoustic distributed Bragg reflectors
(ADBRs) with integrated transducers for high-performance bulk acoustic resonators
(BAW) and possible applications for thermoelectric devices are
presented.
