Gallium arsenide is a technologically important narrow-band-gap semiconductor, in which the excitation of electrons from the valence into the conduction band…
Scientists report the existence of 15 new planets — including one 'super-Earth' that could harbor liquid water — orbiting small, cool stars near our solar…
In semiconductor technology, doping refers to the intentional introduction of impurities (also known as dopants) into a layer or into the intrinsic…
Now a team of researchers from the University of Bristol, Peking University, Technical University of Denmark, ICFO Spain, PAS, University of Copenhagen and Dr….
Semiconductors–a class of materials that can function as both electrical conductor and insulator, depending on the circumstances–are an essential technology…
But in the past two years, with NASA's Juno spacecraft, scientists have gotten a good look at the top and bottom of the planet for the first time. What they…
A visit to the PhotonLab, and what students learn in its course, should ideally stick in their memories. But how can this be done effectively? The PhotonLab at…
Discovered in liquid helium about 80 years ago, superfluidity is a counterintuitive phenomenon, in which quantum physics and particle-wave duality manifest at…
Publishing in a journal like Science Advances usually heralds a particularly exciting innovation. Now, physicists from the Julius-Maximilians-Universität…
In a new paper published today in Science Advances, researchers under the direction of Columbia Engineering Professors Michal Lipson and Alexander Gaeta…
MATISSE is a second-generation Very Large Telescope Interferometer (VLTI) instrument providing extremely high spatial resolution. It is a combined imager and…
New research published in Nature Methods will dramatically improve how scientists “see inside” molecular structures in solution, allowing for much more precise…
“We made these two new discoveries in our large-scale Einstein@Home gamma-ray pulsar survey. This feat was only possible by using novel and more efficient…
The study, by planetary scientists from Brown University, maps the mineralogy of the South Pole-Aitken (SPA) basin, a gash in the lunar surface with a diameter…
When protons accelerated to the greatest energy collide with each other in the LHC, their component particles – quarks and gluons – create a puzzling…
