Substitutional doping from foreign elements stands out as a preferred method for precisely tailoring the electronic band structure, conduction type, and carrier concentration of pristine materials. In the realm of three-dimensional (3D) monocrystalline silicon, for instance, the introduction of boron (B) and nitrogen (N) atoms as acceptor and donor dopants, respectively, has proven highly effective in enhancing carrier mobility. This improvement positions silicon for advanced applications in integrated circuits. https://phys.org/news/2024-01-substitutional-doping-2d-semiconductor-broadband.html Condensed Matter Mon, 08 Jan 2024 14:19:02 EST news623945941 "The price of solar-generated electricity continues to plummet, and the technology is taking over as the least expensive form of energy in more and more parts of the world," says solar cell researcher John Atle Bones at SINTEF. https://phys.org/news/2018-06-robot-vision-solar-cell-efficient.html Robotics Thu, 14 Jun 2018 08:21:29 EDT news448183280 Until now, the metamaterials used to create tunable color from structural geometry have been based on metals. Although effective in achieving high resolutions, metallic materials suffer from inherent energy losses at visible wavelengths, which makes optimizing color purity challenging. By comparison, the resonance of silicon materials enables high reflectance and purity. https://phys.org/news/2018-01-silicon-nanoblock-arrays-vivid-subwavelength.html Nanophysics Thu, 25 Jan 2018 08:47:40 EST news436092450 MIT's Solar Electric Vehicle Team, the oldest such student team in the country, has just finished construction of its latest high-tech car and will be unveiling it to the public this Friday from 3 to 5 p.m. in Lobby 13. https://phys.org/news/2009-02-sleek-mit-solar-car.html Engineering Wed, 25 Feb 2009 15:25:27 EST news154797894
