It's a really exciting time for nanomaterials research because there's a high demand for new materials at the national level - particularly in clean energy. The Center for Integrated Nanotechnologies, an Office of Science National User Facility, offers opportunities for students and researchers at its two New Mexico facilities, Sandia and Los Alamos National Laboratories. To get access to CINT, students and researchers simply need to write a 2-3 page innovative nanoscience proposal. Once accepted, they can access all of the capabilities at CINT for free.
This symposium aims to bring together cutting-edge ideas that would facilitate material innovation for stable perovskite photovoltaics, light emitting diodes and detectors. Recent developments for stable performances in this area include, but are not limited to, novel perovskite nano-structures such as quantum dots, nanowires and nanosheets, hetero-structures formed by perovskites and passivation organic layers or frameworks, and ligand-mediated wavefunction engineering. These advances in material discovery and structural engineering have led to significant progresses in device stability that ranges from environmental stability, electrical field stability and stability under constant irradiation.
In addition to material growth, this symposium will also cover topics on mechanistic understanding of material and device stability through advanced characterization tools, such as operando high resolution spectroscopy and in-situ characterization techniques.
Chemical Synthesis lab enables the design, preparation and integration of optically active semiconductor nanocrystal quantum dots (NQDs) and nanowires (NWs), as well as nanoparticles/nanowires comprising metal oxides, simple metals, and/or magnetic materials. Organometallic, inorganic, organic, colloidal and biochemical synthetic methods can be performed and combined in this lab in order to prepare new precursors, ligands and bi-functional linkers for the synthesis and assembly of novel nanocrystal compositions (e.g., alloys and multi-shell architectures) and structures (e.g., controlled shapes and defined nanocrystal aggregates).
In the eternal search for next generation high-efficiency solar cells and LEDs, scientists at Los Alamos National Laboratory and their partners are gaining an extra degree of freedom in designing and fabricating efficient optoelectronic devices based on 2D layered hybrid perovskites. Industrial applications could include low cost solar cells, LEDs, laser diodes, detectors, and other nano-optoelectronic devices. March 2017

In the CINT Nanostructured Materials Design Lab we are looking beyond typical thin film microstructures and learning how to process unique phase separated thin film morphologies for use in advanced technologies and extreme environments. Physical vapor deposition allows us to precisely control material morphologies that are difficult to develop in bulk materials. 2018
