Surface Rayleigh acoustic waves and related elastic properties of quasiperiodic and periodic modulated a- \(\mathrm{Si}: \mathrm{H} / \mathrm{a}-\mathrm{SiN}_{x}: \mathrm{H}\) superlattices have been studied by means of a light-scattering technique. Changes in the phase velocity of the surface Rayle
By using wavelength modulated absorption (WMA), optical transitions between subbands are revealed in \(\mathrm{a}-\mathrm{Si}: \mathrm{H} / \mathrm{a}-\mathrm{SiN}_{\mathrm{x}}: \mathrm{H}\) superlattices for the well-layer thicknesses less than \(50 \AA\). The threshold energies of the distinct ste
The induced defects and their distribution in a-Si:H/a-SiN x :H multilayers are determined using an electromagnetic technique (EMT) and positron annihilation technique (PAT). It is found that the distributions of the induced defects in the interface regions on both sides of the a-Si:H sublayer are a
