Studies of single doping of Mn and Fe in Si to deduce simple guidelines in selecting transition metal elements for growing Si-based spintronic materials

Michael Shaughnessy, C. Y. Fong, Ryan Snow +3

Single dopings of Mn and Fe in Si are investigated using 8-, 64-, and 216-atom supercells and a first-principles method based on density functional theory. Between the two transiti…

An upper limit on the electron-neutrino flux from the HiRes detector

R. U. Abbasi, T. Abu-Zayyad, M. Allen +64

Air-fluorescence detectors such as the High Resolution Fly's Eye (HiRes) detector are very sensitive to upward-going, Earth-skimming ultrahigh energy electron-neutrino-induced show…
