New Material for Warm-White LED Lights

New Material for Warm-White LED Lights

Light emitting diodes, more commonly called LEDs, are known for their energy efficiency and durability, but the bluish, cold light of current white LEDs has precluded their widespread use for indoor lighting. Now, University of Georgia scientists have fabricated what is thought to be the world’s first LED that emits…

New Design for Basic Component of Computer Chips: Researchers Demonstrate Record-Setting P-Type Transistor

New Design for Basic Component of Computer Chips: Researchers Demonstrate Record-Setting P-Type Transistor

Almost all computer chips use two types of transistors: one called p-type, for positive, and one called n-type, for negative. Improving the performance of the chip as a whole requires parallel improvements in both types. At the IEEE’s International Electron Devices Meeting (IEDM) in December, researchers from MIT’s Microsystems Technology…

Powerful New Tool Is Quantum Analog of Phase Space Flow

Powerful New Tool Is Quantum Analog of Phase Space Flow

UK-based physicist Ole Steuernagel from the University of Hertfordshire, alongside Dimitris Kakofengitis and Georg Ritter, have found that a new powerful tool they call ‘Wigner flow’ is the quantum analogue of phase space flow. Wigner flow provides information for quantum dynamics similar to that gleaned from phase space trajectories in…
