Low Energy Ion Beam Synthesis of Si Nanocrystals for Nonvolatile Memories - Modeling and Process Simulations
Metal-Oxide-Silicon Field-Effect-Transistors with a layer of electrically isolated Si nanocrystals (NCs) embedded in the gate oxide are known to improve conventional floating gate flash memories. Data retention, program and erase speeds as well as the memory operation voltages can be substantially …

Fluorescent silicon nanocrystals for bioimaging
… dyes for fluorescence imaging because they are resistant to photobleaching, exhibit strong response to two-photon excitation, and can be conjugated to a wide variety of targeting molecules. Silicon (Si) nanocrystal quantum dots in particular exhibit bright, size-dependent emission with visible to …

Electronic and optical characterisations of silicon quantum dots and its applications in solar cells
In this thesis, the structural, optical and electrical properties of crystalline silicon quantum dots (SiQDs) are examined for application to silicon based tandem cells. The approach has been to concentrate on all silicon devices by taking advantage of quantum confinement in low-dimensional Si. RF …
