We characterize the optical response of hollow WS2 pyramids, that exhibit a strongly reduced photoluminescence with respect to horizontally layered WS2. Studying the position dependence of the spectral Raman features reveals local variations in the atomic arrangement.

AbstractPhotoreflectance measurements have been performed in the 0.8–1.5 eV photon energy range and at temperatures from 80 to 300 K on stacked layers of InAs/GaAs self-assembled quantum dots (QDs) grown by Atomic-Layer Molecular Beam Epitaxy. The spectral features due to the QD optical response were analyzed by using lineshape models characteristic of modulation spectroscopy of confined systems. The dependence of the ground state transition energy on the number of stacked QD layers is investigated and it is shown that Coulomb interaction can account for the observed different behavior of the ensemble optical response of QD families characterized by different morphologies and coexisting in the same sample.

In order to facilitate widening in optical band gaps utilizing quantum size-effects, self-assembled Si-ncs embedded in an a-Si matrix were grown within a-Si:H/nc-Si:H superlattice thin films produced by alternating sub-layers of a-Si:H and nc-Si:H.
