A group of researchers at the University of California, Riverside Bourns College of Engineering have developed a technique to keep cool a semiconductor material used in everything from traffic lights to electric cars. Gallium Nitride (GaN), a semiconductor material found in bright lights since the 1990s, is used in wireless applications due to its high efficiency and high … [Read more...]
Researchers Use Cold Atoms to Simulate Graphene
Scientists at ETH Zurich used a set of laser beams to create a honeycomb-like structure similar to that found in graphene. By loading ultracold atoms into this optical lattice, they can simulate electronic properties of this promising material. Such experiments may be used to identify electronic properties of materials which have yet to be discovered. Tilman Esslinger, … [Read more...]
Graphene as a Thermal Conductor
A joint U.S.-Chinese research team has demonstrated that the thermal properties of isotopically engineered graphene are superior to those of natural graphene. The demonstration could potentially strengthen the possibility of using graphene to manage heat dissipation. “The important finding is the possibility of a strong enhancement of thermal conduction properties of … [Read more...]
New Graphene Material Conducts Heat Faster than Silicon
A new graphene material capable of conducting heat 20 times faster than silicon could make the next generation of electronic devices quieter and longer-lasting. The experimental graphene made by U.S. and Chinese researchers has also proven 60 percent more effective at transferring heat than typical graphene — a carbon sheet just one atom thick. Efficient heat removal would … [Read more...]
