Following a great success of the three previous similar symposia, this edition addresses the progress in tailoring basic properties of low-dimensional and nano-materials by introducing dopants (e.g., implantation) or creating growth- and radiation-induced defects. The latest achievements in theory and experiment will be presented and discussed by academic and industrial researchers.

  • Following a great success of the three previous similar symposia, this edition of Symposium K "Defect-induced effects in nanomaterials" , organised in the framework of the 2018 E-MRS Spring meeting, addresses the progress in tailoring basic properties of low-dimensional and nano-materials by introducing dopants (e.g., implantation) or creating growth- and radiation-induced defects. The latest achievements in theory and experiment will be presented and discussed by academic and industrial researchers.

    Scope:

    Solids without defects are impossible for thermodynamic reasons. The defects are a Janus Bifrons: they can deteriorate the properties of materials and structures, but they can also provide them with unique and useful properties which are absent in the perfect solids. As we are living more and more in a world replete with manmade nanoobjects, it obviously pays to invest efforts in studies of defects in them. The high sensitivity of modern technologies on the submicron scale has promoted the exciting opportunity of developing new advanced materials with reduced dimensionality. This opens new prospects for ion and electron beam applications. Ion tracks and other radiation-induced effects provide a means for controlled synthesis and modification of low-dimensional materials, such as nanoclusters and nanowires, allowing for efficient nano- and optoelectronic devices. Defect behavior in nanomaterials and nanostructures in its turn has often been found to differ substantially from that observed in bulk materials. Recent work has demonstrated spectacular optical and magnetic effects due to deliberately created defects or radiation-induced transformation of nanomaterials as well as radiation-induced displacements in low-dimensional insulators and semiconductors, with numerous potential applications. We plan to discuss how such defects could be introduced controllably, categorized and controlled in nanostructures. Understanding and controlling defect properties in a wide class of advanced nanostructures (novel 2D materials, multiferroics, quantum dots and wires, etc.) could well be a key to breakthroughs in several crucial areas of science and technology. This is the main focus of the symposium.

    Hot topics to be covered by the symposium:

    • Defects in graphene and other 2D materials
    • Swift heavy ion irradiation as the means to tailor nanomaterials
    • Effects of grain boundaries and interfaces on the diffusion and transport processes in nanomaterials.
    • Electronic structure of defects in nanostructures; consequences for carrier transport, magnetism, optical and electronic properties, as well as device parameters.
    • Creation, evolution and properties of radiation defects in nanosize materials and heterostructures; the role of interfaces, nonstoichiometry, strain and adjacent layers.
    • Use of defects as microprobes.
    • Multiscale computer modeling of defect creation and transformation in nanomaterials.
    • novel technological processes of micro-, nano- and optoelectronics using defects and radiation effects in nanostructures.
