Objective of the researchThe materials under study are thin films and nanomaterials. The common basis is synthetic chemistry and the synthesis products are used precursors for thin films and nanomaterials. The thin films are aimed for microelectronics, photvoltaics, photocatalysis, optics, MEMS, protection etc. The function of the thin film materials can be dielectric, conducting, barrier, hydrophobic or catalytic. As materials they are oxides, metals, nitrides or chalcogenides. The research is basic in nature (new chemistry, reaction mechanisms) but basic properties for the selected appplication areas are characterized as well. The nanomaterials studied are nanotubes, nanofibers, nanoporous materials and nanocomposites. Nanomaterial studies are mostly curiosity driven.Special know-how of the groupThe group has long experience in ALD. The material selection and number of processes studied in ALD is high. Besides ALD, deposition of thin films are made also by other techniques: SILAR, evaporation, spin-coating. In situ reaction mechanism studies in ALD is one of the specialities of the group. Electrospinning of nanofibers and preparation of nanoporous materials are carried out in the group. Synteses of a variety of layered double hydroxide (LDH) based inorganic-organic nanocomposites has been recently developed in the group.Possible utilization of the resultsThe ALD films and processes studied are applicable in microelectronics, optical and protective coatings. Nanocomposites may find applications as biomaterials and in cosmetics.Latest research results
