Tunable Materials Clear the Way for Advanced Optics

Now you see it, now you don’t: In books and movies, wizards use magic spells to easily change things from a solid to see-through state. However, in reality,…

Electronics Get a Power Boost with the Addition of Simple Material

“It’s tough to replace the current transistor technology, because semiconductors do such a fantastic job,” said Roman Engel-Herbert, assistant professor of…

Good Vibrations Give Electrons Excitations That Rock an Insulator to Go Metallic

For more than 50 years, scientists have debated what turns particular oxide insulators, in which electrons barely move, into metals, in which electrons flow…

A Micro-Muscular Break Through

Vanadium dioxide is poised to join the pantheon of superstars in the materials world. Already prized for its extraordinary ability to change size, shape and…

Flexing fingers for micro-robotics: Berkeley Lab scientists create a powerful, microscale actuator

Based on an oxide material that expands and contracts dramatically in response to a small temperature variation, the actuators are smaller than the width of a…

Ultrafast sonograms shed new light on rapid phase transitions

Common phase transitions include the melting of candle wax before it burns and dissolving sugar in water. They are purely structural changes that produce…

ORNL scientists crack materials mystery in vanadium dioxide

Scientists have known that vanadium dioxide exhibits several competing phases when it acts as an insulator at lower temperatures. However, the exact nature of…

Nano-sandwich Triggers Novel Electron Behavior

Working with computational models, the team has found that the electrons in a thin layer of vanadium dioxide sandwiched between insulating sheets of titanium…
