Silicene is a two-dimensional structure composed of a buckled hexagonal honeycomb lattice of silicon atoms. Freestanding silicene is yet to be synthesized, but epitaxial silicene monolayers have been directly observed or predicted to exist on a numbe

Magnesium Double Nitride Mg3GaN3 as New Host Lattice for Eu2+ Doping: Synthesis, Structural Studies, Luminescence, and Band-Gap Determination

Autor: Neil W. Johnson, Frauke Hintze, Alexander Moewes, David Muir, Markus Seibald, Wolfgang Schnick

Publikováno v: Chemistry of Materials. 25:4044-4052

The double nitride Mg3GaN3 and binary nitride Mg3N2 were synthesized from the elements by reaction with NaN3 in a sodium flux. Reactions were carried out at 760 °C in welded shut tantalum ampules. Mg3GaN3 was obtained as single crystals (space group

Oxidized Monolayers of Epitaxial Silicene on Ag(111)

Autor: Neil W. Johnson, Alexander Moewes, David I. Muir

Publikováno v: Scientific Reports

The properties of epitaxial silicene monolayers on Ag(111) at various levels of oxidation are determined through complementary density functional theory calculations and soft X-ray spectroscopy experiments. Our calculations indicate that moderate lev

The electronic structure of lithium metagallate

Autor: Alexander Moewes, Neil W. Johnson, John A. McLeod

Publikováno v: Journal of physics. Condensed matter : an Institute of Physics journal. 23(44)

Herein we present a study of the electronic structure of lithium metagallate (LiGaO(2)), a material of interest in the field of optoelectronics. We use soft x-ray spectroscopy to probe the electronic structure of both the valence and conduction bands
