WebGermanium is an excellent material candidate for various applications, such as field effect transistors and radiation detectors/multijunction solar cells, due to its high carrier mobilities and narrow bandgap, respectively. However, the efficient passivation of germanium surfaces remains challenging. Recently, the most promising results have been achieved … Web20 hours ago · Many physicists regarded the claim warily because 6 months earlier, Nature had retracted a separate room-temperature superconductivity claim from Dias’s group, amid allegations of data manipulation. Now come accusations that Dias plagiarized much of his Ph.D. thesis, completed in 2013 at Washington State University (WSU).
