Mapping of AlxGa1–xAs band edges by ballistic electron emission spectroscopy [PDF]
We have employed ballistic electron emission microscopy (BEEM) to study the energy positions in the conduction band of AlxGa1 – xAs. Epilayers of undoped AlxGa1 – xAs were grown by molecular beam epitaxy on conductive GaAs substrates.

Web-CONEXS: an inroad to theoretical X-ray absorption spectroscopy
Accurate analysis of the rich information contained within X-ray spectra usually calls for detailed electronic structure theory simulations. However, density functional theory (DFT), time-dependent DFT and many-body perturbation theory calculations ...

X-ray absorption branching ratio in actinides: LDA+DMFT approach [PDF]
To investigate the x-ray absorption (XAS) branching ratio from the core 4d to valence 5f states, we set up a theoretical framework by using a combination of density functional theory in the local density approximation and Dynamical Mean Field Theory (LDA+

THE PROSPECT OF GETTING SOLAR CELLS BASED ON GRADED-GAP HETEROSTRUCTURES AlxGa1-xAs - InxGa1-xAs
The paper calculated the structures 2-junction solar cells based on heterostructures of graded-gap AlxGa1-xAs - InxGa1-xAs. It is shown that the efficiency of 2-junction graded-gap solar cells based on heterostructures AlxGa1-xAs - InxGa1-xAs can reach ...

X-ray spectroscopic study of chemical state in uranium carbides
UC and UMeC2 (Me = Fe, Zr, Mo) carbides were studied by the high-energy-resolution fluorescence-detected X-ray absorption (HERFD-XAS) technique at the U M4 and L3 edges.

Effect of 3d-doping on the electronic structure of BaFe2As2 [PDF]
The electronic structure of BaFe2As2 doped with Co, Ni, and Cu has been studied by a variety of experimental and theoretical methods, but a clear picture of the dopant 3d states has not yet emerged.
