There has been significant interest in the development of multicomponent nanocrystals formed by the assembly of two or more different materials with control over size, shape, composition, and spatial orientation. In particular, the selective growth of metals on the tips of semiconductor nanorods and wires can act to couple the electrical and optical properties of semiconductors with the unique ...

Necessity has driven the evolution of microprocessor design practices and CAD tools at Intel Corporation, as the transistor count has grown by a factor of about 4X each processor generation. In order to cope with the complexity of design tasks, Intel's engineers were early adopters and adapters of innovative CAD research from universities. A unique partnership with Alberto’s group in U.C. Berke...

Recent progress in the synthesis and deterministic assembly of advanced classes of single crystalline inorganic semiconductor nanomaterial establishes a foundation for high-performance electronics on bendable, and even elastomeric, substrates. The results allow for classes of systems with capabilities that cannot be reproduced using conventional wafer-based technologies. Specifically, electroni...

Nanocrystals prepared in organic media can be easily self-assembled into close-packed hexagonal monolayers on solvent evaporation for various applications. However, they usually rely on the use of organometallic precursors that are soluble in organic solvents. Herein we report a general protocol to transfer metal ions from an aqueous solution to an organic medium, which involves mixing the aque...

During the past few decades advances in semiconductor technology have had only modest implications for the design and verification of integrated systems. While "deep-submicron" effects created new challenges for guaranteeing electrical integrity and necessitated the bundling of traditionally separated design steps such as logic synthesis and physical layout, the general integrated circuit desig...

In this work we report the synthesis and characterization of a new nanostructured platinum/tin/telluride inorganic/surfactant composite. The material is synthesized from soluble SnTe(4)(4-) clusters and is shown to have well-defined nanometer scale periodicity along with unique optical properties. Small-angle X-ray scattering indicates that the material forms with a 2D hexagonal honeycomb struc...

The synthesis of a high-melting temperature semiconductor in a low-temperature fiber drawing process is demonstrated, substantially expanding the set of materials that can be incorporated into fibers. Reagents in the solid state are arranged in proximate domains within a fiber preform. The preform is fluidized at elevated temperatures and drawn into fiber, reducing the lateral dimensions and br...

Semiconductor tellurium is an excellent performance material, and its compounds have been extensive researched in the low-dimensional field. Inspired by synthesis of a one-dimensional atomic chains, we predict new Te 2 I single-atomic chain structure based on firstprinciples. Using first-principles calculations, has exfoliated energy 137.95 meV, suggesting that exfoliation chains materials from...
