Power/Performance Bits: March 29


Photonic-phononic circuit Researchers at the National Institute of Standards and Technology (NIST) developed a piezo-optomechanical circuit that converts signals among optical, acoustic and radio waves. At the heart of the piezoelectric optomechanical circuit is an optomechanical cavity, which consists of a suspended nanoscale beam. Within the beam are a series of holes that act like a ha... » read more

New switchable material Two MIT researchers developed a thin-film material whose phase and electrical properties can be switched between metallic and semiconducting simply by applying a small voltage. The material then stays in its new configuration until switched back by another voltage. The discovery could pave the way for a new kind of nonvolatile memory. The findings involve the thin-... » read more

Hybrid crystals for efficient LEDs A team from the University of Toronto combined two promising solar cell materials together for the first time, creating a new platform for LED technology. The team designed a way to embed strongly luminescent nanoparticles called colloidal quantum dots into perovskite. Perovskites are a family of materials that can be easily manufactured from solution, a... » read more

Quantum teleportation on a chip Researchers at the University of Tokyo have successfully integrated the core circuits of quantum teleportation, which generate and detect quantum entanglement, into silica-optical-waveguide circuits on a silicon photonic chip measuring 0.0001 square meters. While there has been significant progress in current technology of information processing, its perfor... » read more
