Speech Title Engineering Smart Materials via Atomic-resolution Microscopy and Spectroscopy

Abstract The development of smart catalysts, piezoelectrics, thermoelectrics, light emitting diodes and 2D materials and devices is increasingly important in addressing environmental and energy concerns. The powerful combination of aberration-corrected microscopy and theoretical calculations allows a direct correlation of atomic-scale structure and bonding to materials’ properties, representing a new and efficient approach to materials’ development. A number of illustrative examples will be presented. In catalysis, it has become almost routine to image single atoms and probe their bonding by spectroscopy, greatly aiding development of single atom catalysts (SACs). Their unique coordination can impart exceptional activity and selectivity, and much effort is ongoing to replace platinum group metals by cheaper, earth abundant metals such as cobalt or nickel. Examples include a Co SAC with good activity for both the oxygen evolution and oxygen reduction reactions, and its application as the air cathode in a solid-state Zn−air battery. In nitride-based light-emitting materials, development of an efficient green/red emitting system would further enhance efficiency, but is hampered by the large misfit of high In content GaxIn1-xN on GaN. Recently, by understanding the nucleation of defects, a 9-fold improvement in emission efficiency has been achieved. Improved lead-free piezoelectric materials are also urgently required. By employing atomic-resolution polarization mapping we can uncover the general structural requirements, a coexistence of ferroelectric phases inside nanodomains, and have significantly enhanced the properties of (K,Na)NbO3 and BaTiO3 based lead-free piezoceramics. Nanostructuring is also widely used to enhance thermoelectric properties. Direct observation of intrinsic Pb vacancies and extrinsic Cu interstitials in PbTe reveals the mechanism underlying the optimization of phonon and carrier transport. Recently, doping S into SnSe has markedly improved performance, representing an important step toward low-cost, earth-abundant, environmentally friendly thermoelectrics. In 2D materials, configurations of point defects and their local environments can be directly identified and correlated with properties. It is also possible to selectively sputter light atoms leaving heavier metals atoms intact. In this way we fabricated suspended monolayer Mo membranes from monolayer MoSe2 films, and directly imaged their formation mechanism.

Speech Title Free-standing nanostructures at atomic scale: from growth mechanisms to local properties

Abstract The lack of mirror symmetry in binary semiconductor compounds turns them into polar materials, where two opposite orientations of the same crystallographic direction are possible. Interestingly, their physical properties (e.g.: electronic or photonic) and morphological features (e.g.: shape, growth direction, etc.) also strongly depend on the polarity. It has been observed that nanoscale materials tend to grow with a specific polarity, which can eventually be reversed for very specific growth conditions. In addition, polar-directed growth affects the defect density and topology and might induce eventually the formation of undesirable polarity inversion domains in the nanostructure, which in turn will affect the photonic and electronic final device performance. Here, we present a detailed study on the polarity-driven growth mechanism at the nanoscale, highlighting suitable future possibilities of polarity engineering of semiconductor nanostructures from VLS vertical complex heterostructures to the newest selected area growth hybrid quantum networks. The present study has been extended over a wide range of semiconductor compounds, covering the most commonly synthesized III-V (GaN, GaP, GaAs, GaSb, InN, InP, InAs, InSb) and II-VI (ZnO, ZnTe, CdS, CdSe, CdTe) nanowires and other free-standing nanostructures (tripods, tetrapods, belts and membranes). This systematic study allowed us to explore the parameters that may induce polarity-dependent and polarity-driven growth mechanisms, as well as the polarity related consequences on the physical properties of the nanostructures. The tools used to study the polar nanostructures at the atomic scale will be mainly based on aberration corrected scanning transmission electron microscopy and related spectroscopies. From the structural data obtain we will create 3D atomic models that will allow us to understand the growth mechanisms as well as be used as input data for the further electronic/photonic properties simulations.

Speech Title Toward Reliable and Valid Fracture Toughness Testing for Advanced Ceramic

Abstract There are three methods of applying a force to enable a crack to propagate: Opening mode(Mode I) that is a tensile stress normal to the plane of the crack, Sliding mode (Mode II) that is a shear stress acting parallel to the plane of the crack and perpendicular to the crack front, and Tearing mode (Mode III) which is a shear stress acting parallel to the plane of the crack and parallel to the crack front. Various testing method for fracture toughness mode I(KIC) are introduced in this work and one method was developed for Mode II ( KIIC) measurement is also introduced in this conference. For standard fracture toughness mode I(KIC), an asymmetric bending test was suggested to for in plane stress to occur. The sharp notch can be used for measurement. New type of fracture toughness mode I(KIC) so called ball on three ball fracture toughness test is also introduced.
