WebDec 7, 1992 · These peaks are shown to correspond to 'folded' acoustic phonons with a wavevector close to the incommensurate modulation wavevector. A transverse acoustic mode and a longitudinal mode can be identified in the (ZZ) and (X+Y, Z) polarization configurations, respectively. WebThe folded acoustic modes in a series of InSb/In 1-x Al x Sb (0.2<0.5) strained-layer superlattices were investigated using resonance Raman spectroscopy.

Web1 day ago · For example, a 10-dB increase is a ten-fold increase in acoustic power. A 20-dB increase is then a 100-fold increase in power and a 30-dB increase is a 1000-fold increase in power. However, a ten-fold increase in acoustic power does not mean that the sound is perceived as being ten times louder. Decibels are a relative unit comparing two ... WebApr 1, 2004 · Self-assembled Si/Ge dot multilayers with small, uncorrelated dots fabricated by molecular beam epitaxy in the Stranski–Krastanov growth mode are studied by Raman scattering of folded longitudinal acoustic (FLA) modes.
