Program Highlights for year 2016

All Nanocrystal Electronics

Research

Synthetic methods produce colloidal nanocrystals that are metallic, semiconducting, and insulating. These nanocrystals have been typically used to form only a single component in devices. IRG-4 has exploited the library of colloidal nanocrystals and designed the materials, surfaces, and interfaces to construct all the components of field-effect transistors.

Revealing Hidden Phases in Materials

Research
Strong interactions at the interface between a crystalline film and substrate can impart new structure to thin films. Here, a germanium surface (purple atoms) squeezes a BaTiO3 thin film above, revealing a hidden phase not seen in the bulk. The hidden phase of BaTiO3 shows oxygen octahedra cages (shaded in aqua) alternating in size. By combining theory, synchrotron x-ray diffraction, and electron microscopy, a new materials design approach has uncovered hidden traits of a material that can be expressed through articulated forces at an interface.

Electrocatalytic Surfaces Using Bulk Metallic Glass Nanostructures

Research
Metallic glass nanostructures provide a new platform for electrocatalytic applications. Several surface modification strategies that remove or add metal species (top images) improve the catalytic activity of metallic glass nanostructures. These strategies were demonstrated for three key electrocatalytic reactions important for renewable energy.
