AB INITIO OPTICAL PROPERTIES OF SI(100)

We compute the linear optical properties of different reconstructions of the clean and hydrogenated Si(100) surface within DFT-LDA, using norm-conserving pseudopotentials. The equilibrium atomic geometries of the surfaces, determined from self-consistent total-energy calculations within the Car-Parrinello scheme, strongly influence reflectance anisotropy spectra, showing differences between the

Second-harmonic microscopy of strain fields around through-silicon-vias

We present a model for second-harmonic generation in a two-dimensional array of quantum dots. We show that the combined effect of the electromagnetic local field of the array and the intrinsic electronic resonances that arise from spatial confinement in the quantum dot produces great enhancements of the second-order nonlinear susceptibilities, hence giving a high efficiency of second-harmonic generation.
