A 1k silicon oxide memory has been assembled by Rice and a commercial partner as a proof-of-concept. Silicon nanowire forms when charge is pumped through the silicon oxide, creating a two-terminal resistive switch.

The metamaterial patterns are directly sculpted on the highly doped GaAs facet of the device. Artificial coloring in the figure indicates deep and shallow micron scale grooves, which have different functions. The shallow "blue" grooves efficiently couple laser output into surface electromagnetic waves on the facet and confine the waves to the facet. (Credit: Courtesy [...]

A new battery demonstrated a power output 10 times higher, for its size, than what is expected of a conventional rechargeable lithium battery BETTER BATTERIES: Scientists have used carbon nanotubes to increase the capacity and power output of conventional rechargeable lithium batteries. Imagine that the same rechargeable battery in your cell phone could power a [...]

A flexible array of gallium arsenide solar cells. Gallium arsenide and other compound semiconductors are more efficient than the more commonly used silicon. (Credit: John Rogers) ScienceDaily (May 24, 2010) — Thanks to a new semiconductor manufacturing method pioneered at the University of Illinois, the future of solar energy just got brighter. Although silicon is [...]

Colorized micrograph of superconducting circuit used in NIST quantum computing research. The chip combines a quantum bit (pink) for storing quantum information, a quantum bus (green) for transporting information, and a switch (purple) that "tunes" interactions between the other two components.

3D rendered image showing a heated nanoscale silicon tip, borrowed from atomic force microscopy that is chiselling away material from a substrate to create a nanoscale 3D map of the world. As reported in the scientific journal Advanced Materials, IBM Researchers used this new nanopatterning technique to create the smallest map of the world in [...]

The economics of the electronics industry depends on its ability to carve thousands of microchips simultaneously from silicon wafers the size of dinner plates. Lacklustre – but a sparkling green tech future? (Image: AIST) A new generation of greener, more powerful electronics could be born if we could make those wafers from a material that [...]

The centerpiece of the new microlaser is the electric resonator, consisting of two semi-circular capacitors that are connected via an inductor (here, a scanning electron microscope image). The color intensity represents the strength of the electrical field; the color itself, the respective polarity.

ScienceDaily (Apr. 4, 2010) — A team of researchers at MIT has made significant progress on a technology that could lead to batteries with up to three times the energy density of any battery that currently exists. Test battery has inlet and outlet on the sides to provide a flow of air, providing oxygen for [...]

The sensor recognizes the finger's heat signal without being touched. (Credit: Copyright image/Joanneum Research Forschungsgesellschaft mbH) ScienceDaily (Mar. 31, 2010) — The cellphone is switched off but immediately springs into action at the point of a finger. It is not necessary to touch the display. This touchless control is made possible by a polymer sensor [...]
