Luminescent Eu3+ doped Al6Ge2O13 crystalline compounds obtained by the sol gel process for photonics
(2018-01-01)
We synthesized pure and Eu3+ doped Al6Ge2O13 samples by an easy and low-cost sol-gel route using the GeO2, Al(NO3)3·9H2O and Eu(NO3)3·6H2O as precursors, tetramethylammonium hydroxide and ethanol as solvents. The Al6Ge2O13 ...
The effect of additional Si and SiGe layers on the confinement potential of GeMn diluted ferromagnetic semiconductor
(ELSEVIER SCIENCE BV, 2008)
In this work we analyze the spin-polarized charge density distribution in the GeMn diluted ferromagnetic semiconductors (DFS). The calculations are performed within a self-consistent k.p method, in which the exchange ...

The composition, structure and optical properties of weakly magnetic Co-containing amorphous Si and Ge films
(ElsevierLausanne, 2012-05)
This study investigated the composition, structure and optical properties of amorphous SiCo and GeCo films. The samples were prepared by radio frequency sputtering. Films were deposited with Co atomic concentrations in the ...
Magnetostriction of polycrystalline Fe-Ge alloys
(ELSEVIER SCIENCE SA, 2009)
The longitudinal and transverse magnetostriction and microstructure of polycrystalline Fe(100-x)Ge(x) (x= 8, 12, 15, 20) alloys were investigated in order to correlate the magnetostriction with microstructure. In order to ...
