It's a really exciting time for nanomaterials research because there's a high demand for new materials at the national level. 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
The versatile K3 IS direct detection camera is allowing for in-situ
characterization of material reactions with high ease-of-use and unhindered switching between low-dose and high-speed imaging. The large field of view with the K3 IS camera has enabled investigations on nanoparticle transformations and dynamics at temperature within the environmental TEM, lithiation of battery anodes, and 4D STEM strain mapping of nanowires post in-situ testing. Additionally, the low dose functionality has been paired with cryogenic imaging of beam-sensitive materials including battery electrodes/electrolytes and metal-organic frameworks. Beam-sensitive environmental imaging takes advantage of this advanced camera for real-time frame averaged viewing prior to the collection of stimulated events in the sample, where the look-back feature prevents crucial images from being lost. This webinar highlights the functionality of the K3 IS camera for in-situ and low-dose imaging of an array of reactions and materials, to showcase its versatility and user-friendly capabilities. Our work specializes in in-situ studies, where fast reactions and beam-sensitive materials will be covered in the most detail. Presenters: Katherine Jungjohann, Ph.D. from the Center for Integrated Nanotechnologies, Sandia National Laboratories John Watt, Ph.D. from the Center for Integrated Nanotechnologies, Los Alamos National Laboratory.
CINT Manager Ryan Wixom discusses CINT's mission as a national resource for research expertise and capabilities in the area of nanoscience and the center's vision for the future of nanoscience, which involves integrating nanostructured materials to exploit their unique properties. Podcast
"All Things Photonics" As separate disciplines, quantum science and integrated photonics are pushing the bounds of possibility in communication science, compute, data processing, and more. In tandem, the two realms are highly complementary. CINT Affiliate Scientist Matt Eichenfield, the SPIE Endowed Chair in Optical Sciences and associate professor of optical sciences at the University of Arizona Wyant College of Optical Sciences, spotlights quantum integrated photonics with a focus on applications and a look into the future of the field.
