Two quantum dots are better than one: Using one dot to sense changes in another![]() Osaka, Japan (SPX) Sep 27, 2018 Quantum dots are nanometer-sized boxes that have attracted huge scientific interest for use in nanotechnology because their properties obey quantum mechanics and are requisites to develop advanced electronic and photonic devices. Quantum dots that self-assemble during their formation are particularly attractive as tunable light emitters in nanoelectronic devices and to study quantum physics because of their quantized transport behavior. It is important to develop a way to measure the charge in a s ... read more |

How long does a quantum jump take? Vienna, Austria (SPX) Sep 25, 2018
It was one of the crucial experiments in quantum physics: when light falls on certain materials, electrons are released from the surface. Albert Einstein was the first to explain this phenomenon in 1905, when he spoke of "light quanta" - the smallest units of light that we call photons today.
In tiny fractions of a second, an electron of the material absorbs a photon, "jumps" into another ... more |
