Researchers have created the first transistors made of silicene, the world's thinnest silicon material. Their research holds the promise of building dramatically faster, smaller and more efficient computer chips.
Berkeley Lab researchers have developed a nano-sized optical antenna that can greatly enhance the spontaneous emission of light from atoms, molecules and semiconductor quantum dots. This advance opens the door to light-emitting diodes (LEDs) that can replace lasers for short-range optical communications, including optical interconnects for microchips, plus a host of other potential applications.
Small magnetic whirls may revolutionize future data storage and information processing if they can be moved rapidly and reliably in small structures. A team of scientists has now been able to investigate the dynamics of these whirls experimentally.
