First, it was the soccer-ball-shaped molecules dubbed buckyballs. Then it was the cylindrically shaped nanotubes. Now, the hottest new material in physics and nanotechnology is graphene: a remarkably flat molecule made of carbon atoms arranged in hexagonal rings much like molecular chicken wire.
For the first time, it has been possible to measure electron density in individual molecular states using what is known as the photoelectric effect. Now published in SCIENCE, this method represents a key building block in the development of organic semiconductor elements.
According to a recent report by the National Research Council of the National Academy of Sciences, the United States, once the world leader in the discovery and growth of crystalline materials, is
North Carolina State University engineers have created a new material that would allow a fingernail-size computer chip to store the equivalent of 20 high-definition DVDs or 250 million pages of text, far exceeding the storage capacities of today's computer memory systems.
NEW BRUNSWICK, N.J. -- Rutgers researchers have discovered novel electronic properties in two-dimensional sheets of carbon atoms called graphene that could one day be the heart of speedy and powerful electronic devices.
COLUMBUS, Ohio -- Small bits of metal may play a new role in solar power.
Researchers at Ohio State University are experimenting with polymer semiconductors that absorb the sun's energy and generate electricity. The goal: lighter, cheaper, and more-flexible solar cells.
Berkeley -- Researchers at the University of California, Berkeley, have reached a new milestone in laser physics by creating the world's smallest semiconductor laser, capable of generating visible light in a space smaller than a single protein molecule.
Ever since graphene was discovered in 2004, this one-atom thick, super strong, carbon-based electrical conductor has been billed as a "wonder material" that some physicists think could one day replace silicon in computer chips.
BERKELEY, CA -- Researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory and the University of California at Berkeley have demonstrated a way to fabricate efficient solar cells from low-cost and flexible materials.
ANN ARBOR, Mich.---Physicists have found a way to drastically prolong the shelf life of quantum bits, the 0s and 1s of quantum computers.
University of Georgia researchers have developed a successful way to grow molecular wire brushes that conduct electrical charges, a first step in developing biological fuel cells that could power pacemakers, cochlear implants and prosthetic limbs. The journal Chemical Science calls the technique "a significant breakthrough for nanotechnology."
