Observation of hypersonic phononic crystal effects in porous silicon superlattices [PDF]
, 2009 Brillouin light scattering experiments were carried out on porous silicon superlattices with modulation wavelengths in the range 37–167 nm. Phonon frequencies deduced from the Brillouin spectra show good agreement with those obtained from an elastic ...
