Oxidized GaN(0001) surfaces studied by scanning tunneling microscopy and spectroscopy and by first-principles theory
Oxidized Ga-polar GaN surfaces have been studied both experimentally and theoretically. For in-situ oxidization at 550°C using molecular oxygen, Auger electron spectroscopy indicates a saturation oxygen coverage of 2.1 ± 0.5 monolayers. For these surfaces scanning tunneling microscopy reveals two surface phases, one with ° − × 30 3 3 3 3 R periodicity and the other with disordered 2× periodicit...
متن کاملAtomic-Scale Structure of η-phase Mn3N2 (010) Studied by Scanning Tunneling Microscopy and First-Principles Theory
The (010) surface of η-phase Mn3N2 grown on MgO(001) by molecular beam epitaxy is studied using scanning tunneling microscopy. The images show that the surface is composed of rows with spacing of 6.07 Å. Two types of domains with their c-planes perpendicular are observed in which the domain boundary is oriented at ∼ 45◦ to the c-planes. In other cases, the angle between the c-planes of the two ...
متن کاملGaN(0001) Surface Structures Studied Using Scanning Tunneling Microscopy and First-Principles Total Energy Calculations
Surface reconstructions occurring on the (0001) surface of wurtzite GaN are studied using scanning tunneling microscopy, electron diffraction, and Auger electron spectroscopy. The family of reconstructions found on this face includes 2×2, 5×5, 6×4, and “1×1”, in order of increasing surface Ga/ N ratio. Detailed experimental results are presented for each of these reconstructions. First-principl...

متن کاملMetal-silicene interaction studied by scanning tunneling microscopy.
Ag atoms have been deposited on 3 × 3 silicene and √3 × √3 silicene films by molecular beam epitaxy method in ultrahigh vacuum. Using scanning tunneling microscopy and Raman spectroscopy, we found that Ag atoms do not form chemical bonds with both 3 × 3 silicene and √3 × √3 silicene films, which is due to the chemically inert surface of silicene. On 3 × 3 silicene films, Ag atoms mo...
