Local electronic structure of Fe$^{2+}$ impurities in MgO thin films: Temperature-dependent soft x-ray absorption spectroscopy study
Local electronic structure of Fe$^{2+}$ impurities Temperature-dependent soft x-ray absorption spectroscopy study
2010/11/18
We report on the local electronic structure of Fe impurities in MgO thin films. Using soft x-ray absorption spectroscopy (XAS) we verified that the Fe impurities are all in the 2+ valence state.The fi...

Two-photon Absorption Processes in Semiconductor Quantum Dots
Nonlinear absorption Two-photon absorption Quantum dots
2010/9/29
The two-photon absorption process is a nonlinear phenomenon that shows very low optical efficiency in bulk
semiconductors. For this reason the detection of these processes becomes very difficult from...
New Phases of YBaCuGeO Superconductors Identified from X-ray Diffraction and Infra-red Absorption Measurements
Superconductors X-ray Infra-red YBCO Ge
2010/4/12
X-ray powder diffraction patterns and infra-red absorption spectra have been evaluated and analysed for the Y1 Ba2 Cu3 O7-d - Gex compound samples prepared by the solid state reaction with x values ra...
Magnetic Field Induced Absorption in PbxEu1-xTe Magnetic Semiconductors
Magnetic Field Absorption PbxEu1-xTe Magnetic Semiconductors
2010/10/22
We report an investigation of the optical absorption spectrum, using non-polarized light, in PbxEu1¡xTe, x=0 and x=0.095, epitaxial thick layers grown by molecular beam epitaxy (MBE). The absorp...
The Absorption Properties of p-Type TlInx Ga(1-x) Se2 and TlGaSe2
TlGaSe2 TlIn0.3Ga0.7Se2 TlIn0.5Ga0.5Se2 single crystals absorption binding energy phase transition
2010/4/15
p-TlGaSe2, p-TlIn0.3Ga0.7Se2 and p-TlIn0.5Ga0.5Se2 single crystals were grown by the modified Bridgman-Stockbarger method in our crystal growth laboratory. The absorption measurements were carried out...
Optical spectroscopy methods are used to study the spectra of some oxygen-octahedral ferroelectrics - LiNbO3 and LiTaO3. Study of the role of BO6 octahedron by using spectroscopic methods can cast lig...
Low-Magnetic Field Microwave Absorption in Superconductors and Conducting Polymers
microwave absorption low-field signal
2010/4/15
Low-magnetic field microwave absorption (MA) in superconductors and conducting polymers is analysed in a low-field signal (LFS) version of the MA detecting method. The temperature dependences, hystere...
