Microelectronic Engineering, 2004
In this paper, we present an overview of memory structures fabricated by our group by using silicon nanocrystals as storage nodes. These devices show promising characteristics as candidates for future deep-submicron non-volatile memories.

Two-Photon-Pumped Perovskite Semiconductor Nanocrystal Lasers.
Journal of the American Chemical Society, 2016Two-photon-pumped lasers have been regarded as a promising strategy to achieve frequency up-conversion for situations where the condition of phase matching required by conventional approaches cannot be fulfilled.

Journal of Crystal Growth, 1998
Abstract The excitation energies can be described in the frame of the effective mass approximation when the crystals are not too small. The lowest energy exciton state is split in several sublevels by the electron—hole exchange interaction and by the crystal field in wurtzite-type semiconductors.

Theory Of Silicon Nanocrystals
2003The intense luminescence observed for porous silicon [1] has raised extremely interesting problems related to the possibility of using silicon in optoelectronics. One likely explanation is quantum confinement, induced by the formation of nanocrystallites.

The Assembly of Coated Nanocrystals*
The Journal of Physical Chemistry B, 2003The formation of nanostructured materials through the assembly of nanocrystals is described, focusing in particular on silica and other metal oxide coated core particles. The preparation and optical characterization of core−shell materials are reviewed, and some of the unique properties of core−shell materials are presented.

The surface science of nanocrystals
Nature Materials, 2016All nanomaterials share a common feature of large surface-to-volume ratio, making their surfaces the dominant player in many physical and chemical processes. Surface ligands - molecules that bind to the surface - are an essential component of nanomaterial synthesis, processing and application.
