Particle Shape Affects Membrane Bending & Drop Drying

Novel, cylindrical, ribbon-like membranes are formed when colloidal particles adsorb at the air-water interfaces of droplets confined between two glass plates (Fig. a). We have found that the ease with which such ribbon membranes bend depends on particle shape.

Topological Semimetal in Tensile Strained HgTe

In the past few years, the theory of topological band structures has been generalized beyond topological insulators to include topological semimetals, including Weyl semimetals, Dirac semimetals and other “symmetry protected” topological states.  HgTe is a semimetal in which the degeneracy of the conduction and valence band at the G point is protected by symmetry.  In their early work on topolo

A Range of Amorphous Structures

A range of amorphous structures for a single chemical-composition material (Indium Oxide) were observed; the structure dependent on the growth conditions. The carrier mobility and film (not carrier) density of the films was dependent on growth temperature.

High Performance Carbon Nanotube Thin-Film Transistors Enabled by Hybrid Molecular Dielectrics

Over the past decade, semiconducting carbon nanotube (CNT) thin films have been recognized as contending materials for a wide range of applications in electronics, energy, and sensing. Nevertheless, CNT transistor performance suitable for real-world applications awaits understanding-based progress in the integration of independently pioneered device components.

Triangle Small Angle X-Ray Scattering Facility

In an effort, spearheaded by Triangle MRSEC, we received support through the NSF-MRI program for the purchase of Small Angle X-Ray Scattering (SAXS) instrumentation. The state-of-the-art instruments will serve the greater Research Triangle community for research and education, and will be housed in Duke's Shared Materials Instrumentation Facility (SMIF).
