Strain coefficient measurement for the (100) uniaxial strain silicon by Raman spectroscopy

Detecting compressive strain by evaluation of Raman spectroscopy of the multiwall Carbon nanotubes/TiO2 nanocomposites

Functionalized Multi-walled carbon nanotubes (f-MWCNTs) which are modified using nitric acid and sulfuric acid were evaluated to synthesize a uniform nanocomposite via application of TiO2. The f-MWCNTs-TiO2 nanocomposites have been produced via using the chemical simple two-step method. To characterize the structural analysis, scanning electron microscopy...

Quantification of the bond-angle dispersion by Raman spectroscopy and the strain energy of amorphous silicon

A thorough critical analysis of the theoretical relationships between the bond-angle dispersion in a-Si, , and the width of the transverse optical Raman peak, , is presented. It is shown that the discrepancies between them are drastically reduced when unified definitions for and are used. This reduced dispersion in the predicted values of together with the broad agreement with the scarce direct...
