Researchers create a wire 4 atoms wide, 1 atom tall

The smallest wires ever developed in silicon - just one atom tall and four atoms wide - have been shown by a team of researchers from the University of New South Wales, Melbourne University and Purdue University to have the same current-carrying capability as copper wires.

Using UV light to write on a DNA information-storage device

In an effort to make data storage more cost-effective, a group of researchers from National Tsing Hua University in Taiwan and the Karlsruhe Institute of Technology in Germany have created a DNA-based memory device that is "write-once-read-many-times" (WORM), and that uses ultraviolet (UV) light to make it possible to encode information.

Graphene's piezoelectric promise

Engineers at the University of Houston have used quantum mechanical calculations to show that, merely by creating holes of a certain configuration in a sheet of graphene, they can coax graphene into behaving like a piezoelectric material.

SSRL helps Stanford scientists study enhanced organic semiconductor

Organic semiconductors could usher in an era of foldable smartphones, better high-definition television screens and clothing made of materials that can harvest energy from the sun needed to charge your iPad, but there is one serious drawback: organic semiconductors do not conduct electricity very well. Researchers at Stanford have changed that equation by improving the ability of the electrons to move through organic semiconductors.
