Jun 02, 2023 (Nanowerk News) Usually, the two characterizations of a material are mutually exclusive: something is either stiff, or it can absorb vibrations well – but rarely both. However, if we could make materials that are both stiff and good at absorbing vibrations, there would be a whole host...
Mysterious dashes revealed in Milky Way’s center
Jun 02, 2023 (Nanowerk News) An international team of astrophysicists has discovered something wholly new, hidden in the center of the Milky Way galaxy. In the early 1980s, Northwestern University’s Farhad Yusef-Zadeh discovered gigantic, one-dimensional filaments dangling vertically near Sagittarius A*, our galaxy’s central supermassive black hole. Now, Yusef-Zadeh and...
Proof of concept demonstrates electrons move faster in germanium tin than in silicon or germanium
Jun 02, 2023 (Nanowerk News) CEA-Leti research scientists have demonstrated that electrons and other charge carriers can move faster in germanium tin than in silicon or germanium, enabling lower operation voltages and smaller footprints in vertical than in planar devices. This proof-of-concept breakthrough means vertical transistors made of germanium tin...
