Effects Electron Back-scattering Observations Cross-sectioned GaAs/AlAs Superlattice Auger Electron Spectroscopy
2010/9/17
Cross-sections of GaAs/AlAs thin films prepared by cleavage of MBE-grown superlattices have been analyzed with Auger electron spectroscopy with a spatial resolution of 6 nm. Elemental distributions o...
Dynamic light back-scattering with polarization gating and Fourier spatial filter for particle sizing in concentrated suspension
particle sizing dynamic light scattering back-scattering polarization gating Fourier spatial filter

We present here a new dynamic light scattering method for investigating the particle size in
concentrated suspension. By using the polarization gating and Fourier spatial filter, the optical
thickne...
