Residual gases analysis after dissociation of tetramethylsilane (TMS) during the synthesis of silicon carbide (SiC) nanocrystals (NCs) by an atmospheric pressure microplasma was used to provide details that can contribute to the understanding of the formation mechanisms of NCs (Plasma Processes and Polymers 17, 2020, 1900243).
Professor Davide Mariotti has been ranked in the top 2% of World Scientists, and top UU expert in Applied physics, Nanoscience and Nanotechnology (@UUEngineering).
The relationship between the crystallization process and opto-electronic properties of silicon quantum dots (Si QDs) synthesized by atmospheric pressure plasmas (APPs) is studied in this work. We measure the ultraviolet-visible optical properties and electronic properties through various techniques, build an energy level diagram for the valence electrons region as a function of the crystallinity of the QDs, and finally discuss the integration of these as active layers of all-inorganic solar cells (Faraday Discussions 222, 2020, 390).
Nanofluids comprised of nanoparticles in ethylene glycol have been prepared. The energy absorptive properties of the prepared nanofluids were investigated as a potential additive to the traditional working fluids used in solar thermal collectors. The application feasibility has been assessed by calculating a value of power which could be transferred to the thermal
fluid (Solar Energy 203, 2020, 37).
Strongly confined ligand-free, defect-free, hydroxy terminated ZnO quantum dots with a mean diameter of 1.9 nm were synthesized by radio frequency atmospheric pressure microplasma. Photoluminescence studies show strong confinement effect on emission with only ultraviolet (UV) emission without any defect-related visible emission. The mechanism responsible for this UV emission is also discussed and originates from OH-related surface terminations (Nanotechnology 31, 2020, 215707).
Highly stable zero-dimensional (CH3NH3)3Bi2I9 photovoltaic cells which demonstrate a 33% increase in performance after 2 years when hybridized with silicon nanocrystals (SiNCs) (Nanoscale Advances 1, 2019, 4683).
