Foldable and stretchable, silicon circuits conform to many shapes

Circuit diagram (top frame) and optical images of a stretchable, "wavy" silicon ring oscillator circuit on a rubber substrate, in the "as fabricated" flat state (top micrograph) and in moderate and high states of biaxial compression (middle and bottom micrographs, respectively).

'Quantum Hall-like effect' found in a bulk material without an applied magnetic field

Apr 25, 2008
These images collected by Princeton University scientists show (top) the first direct image of the dancing pattern of electrons on the edge of the bismuth-antimony bulk crystal, which is a quantum Hall insulator; (center) ...

Creating Faster Integrated Circuits by Slowing Light

Apr 24, 2008
A section of the coupled-resonator slow-wave structure in silicon fabricated using electron-beam lithography. The full structure consists of one hundred coupled cuboidal resonators connected sequentially by a thin photonic-wire ...

Simulation shows how defect-engineered zirconia repairs radiation-induced damage

Apr 17, 2008
In yttria-stabilized zirconia (top), the defects produced by radiation are few and far between, having less impact on the properties of the material. In zircon (bottom), the defects are clustered, which could compromise the ...
