The NSF NeXUS user facility is designed to enable direct observation of electron motion with attosecond femtosecond time resolution, angstrom spatial and element-specific spectral resolution. will level the scientific playing field by providing researchers across disciplines access most advanced characterization tools available worldwide for studying ultrafast dynamics in molecules materials.
We have studied the optical band and defect transitions of ScN, a group IIIB transition metal nitride semiconductor with electronic optoelectronic applications. Recent works focused on degenerate nature ScN by substitutional impurities ON FN, which shift direct (X–X) gap to higher energies via Burstein–Moss effect. used cathodoluminescence spectroscopy (CLS) observe signatures both midgap VN precursor doping as well above bandgap corresponding band-to-band from four separate conduction bands...
The graphane analogues of group 14 are a unique family 2D materials due to the necessity terminal ligand for stability. Here we highlight how changing surface can lead nonobvious interactions with other chemical species. We show using XRD, FTIR, and TGA that GeCH3 reversibly absorbs water into van der Waals space, whereas GeH does not intercalate water. Molecular dynamics density functional theory simulations predict datively interacts Ge–C σ* pocket on Ge framework, resulting in local...
The Cu(100) surface offers a model platform for the investigation of copper oxidation process, and oxide-CO2 interaction. Starting from clean Cu(100), we characterized oxidized surfaces with varying oxygen exposure, sample temperature, post-oxidation annealing conditions. Scanning tunneling microscopy was used to characterize atomic resolution imaging at 78 K. Annealing in O2 (P~ 5·10-6 mbar) 80-260 °C led (2√2 x √2) R45° Cu(100)-O missing row reconstruction (MRR), which self-limited...
Initially developed to defeat the increasing threat of improvised explosive devices (IED) during height Iraq War in 2003, DTRA/JD quickly evolved into Department Defense’s (DoD) main effort countering and reducing effect threats. Following a suggestion from about project leads, our team reached out AFRICOM began working on problem narrowly tailored toward their mission. AFRICOM’s strategic focus East Africa complex situation involving refugees internally displaced persons region require...
