Electron spectroscopy in narrow band f-electron compounds

Positron Annihilation Studies of f-Electron Compounds

We present a theoretical analysis of positron annihilation studies of two isostructural f -electron compounds CeIn3 and UGa3. The interpretation of twodimensional angular correlation of annihilation radiation experiment (2D-ACAR) is based on a parameter-free density functional theory calculations. Our analyses show, that the f -electrons in CeIn3 behave as well localized while in UGa3 it was th...

Superconducting phases of f-electron compounds

Intermetallic compounds containing f-electron elements display a wealth of superconducting phases, that are prime candidates for unconventional pairing with complex order parameter symmetries. For instance, superconductivity has been found at the border of magnetic order as well as deep within ferroand antiferromagnetically ordered states, suggesting that magnetism may promote rather than destr...

Band-Gap Tuning Of Electron Beam Evaporated Cds Thin Films

The effect of evaporation rate on structural, morphological and optical properties of electron beam evaporated CdS thin films have been investigated. CdS thin film deposited by electron beam evaporation method in 12nm/min and 60nm/min evaporation rates on glass substrates. X-ray diffraction, scanning electron microscopy, UV-Vis-NIR spectroscopy and Atomic Force Microscopy were used to character...

Mapping of AlxGa12xAs band edges by ballistic electron emission spectroscopy

We have employed ballistic electron emission microscopy ~BEEM! to study the energy positions in the conduction band of AlxGa12xAs. Epilayers of undoped AlxGa12xAs were grown by molecular beam epitaxy on conductive GaAs substrates. The Al composition x took on values of 0, 0.11, 0.19, 0.25, 0.50, 0.80 and 1 so that the material was examined in both the direct and indirect band gap regime. The Al...
