Sandia Develops Phased-Array Sources Based on Nonlinear Metamaterial Nanocavities

The SH-generating quantum well layer (pink) and the beam-shaping split-ring metamaterial resonators (the “C”-shaped structures). The phase-coherent emission from individual resonators opens the door for many beam-shaping applications, some of which are presented in the insets. Each device type can be achieved via proper design of individual metamaterial resonators and their arrangement on the [...]

Novel Nanoparticle Production Method Could Lead to Better Lights, Lenses, Solar Cells

Sandia researchers Dale Huber (left) and Todd Monson have come up with an inexpensive way to synthesize TiO2 nanoparticles, which could be used in everything from solar cells to light-emitting diodes. (Photo by Randy Montoya) Titanium-dioxide (TiO2) nanoparticles show great promise as fillers to tune the refractive index of anti-reflective coatings on signs [...]

Sandia/CINT Research on the Cover of Applied Physics Letters

A recent publication, “Few-hole double quantum dot in an undoped GaAs/AlGaAs heterostructure,” by Lisa Tracy (in Sandia’s Quantum Phenomena Dept.) and Terry Hargett and John Reno (both in Sandia’s Nanostructure Physics Dept.), was selected as the cover article for the current issue of Applied Physics Letters. They demonstrate a hole double quantum dot in an [...]

CINT Computer Simulation Guide for Designing Polymeric Nanoparticles Published

Monomer chemical structure (top right), the nanoparticle, as made (top left) and in equilibrium in water. The curves in the center correspond to the static structure factor S(q) as the function of q for polymer substituted (solid triangles) and without (open triangles) side chains in water with best fit to a fuzzy spherical form [...]

Sandia, Los Alamos, Superconducting Technologies Inc., & Superpower: Solution Deposition Planarization

The nation’s electricity grid relies on power transmission from the production source—be it a coal-fired plant, solar array, or wind farm—to the consumer. Long-distance transmission results in sizeable energy losses due to resistance in the conducting material. Superconducting wires offer the potential for zero power dissipation and higher maximum current densities when contrasted with traditional [...]

Sandia Demonstrated First-Time, Single-Mode Lasing in Gallium-Nitride Nanowire Lasers

An array of GaN nanowires. Semiconductor nanowire lasers have attracted intense interest as promising compact, low-power coherent light sources for on-chip applications, many of which (e.g., imaging, multiplex communica­tion, data storage) desire high beam quality and spectral purity—conditions that can be satisfied by single-mode operation in nanowire lasers. However, due to the lack of [...]

Sandia to Study the Little Things

The Center for Integrated Nanotechnologies at Sandia recently received a $900,000 grant to investigate the tiniest parts of solar materials. The new grant, announced by the U.S. Department of Energy in late August, will fund development of new microscopy tools to help understand the chemical and electronic structure of thin-film photovoltaic, or solar, materials and how microscopic [...]
