Vibrating nanorods measure thin films for microcircuits

A key step in many nanofabrication processes is to create thin films, sometimes only one molecule thick, by a method known as atomic layer deposition. Researchers at Cornell and Tel Aviv University have developed a new tool for nanofabricators to test the physical properties of such films.

Technique turns computer chip defects into an advantage

Physicists at Ohio State University have discovered that tiny defects inside a computer chip can be used to tune the properties of key atoms in the chip. The technique involves rearranging the holes left by missing atoms to tune the properties of dopants - the chemical impurities that give the semiconductors in computer chips their special properties.

NIST's new scanning probe microscope is supercool

The discoveries of superconductivity, the quantum Hall effect and the fractional quantum Hall effect were all the result of measurements made at increasingly lower temperatures. Now, pushing the regime of the very cold into the very small, a research team from the National Institute of Standards and Technology (NIST), the University of Maryland, Janis Research Company, Inc., and Seoul National University, has designed and built the most advanced ultra-low temperature scanning probe microscope (ULTSPM) in the world.
