UM: ‘Photon Glue’ Enables New Quantum State That Could Mean Better Lighting, Solar Cells

Like a spring connecting two swings, light can act as a glue that binds together the quantum mechanical properties of two vastly different materials used for electronics. The effect could harness the most useful characteristics from each material for hybrid solar cells and high efficiency lighting.

Beyond Silicon: Michigan Tech Pioneering Transistors Sans Semiconductors

For decades, electronic devices have been getting smaller, and smaller, and smaller. It’s now possible — even routine — to place millions of transistors on a single silicon chip. But silicon transistors can only get so small. Now, researchers at Michigan Technological University are making transistors out of nanotubes — which allows much smaller structures.
