Ultrahigh nitrogen-vacancy center concentration in diamond
S. Kollarics, F. Simon, A. Bojtor +19
High concentration of negatively charged nitrogen-vacancy () centers was created in diamond single crystals containing approximately 100 ppm nitrogen using electron…
Formation of Cu6Sn5 phase by cold homogenization in nanocrystalline Cu-Sn bilayers at room temperature
H. Zaka, S. S. Shenouda, S. S. Fouad +5
Solid state reaction between nanocrystalline Cu and Sn films was investigated at room temperature by depth profiling with secondary neutral mass spectrometry and by X-ray diffracti…
Transition from anomalous kinetics towards Fickian diffusion for Si dissolution into amorphous Ge
Z. Balogh, Z. Erdelyi, D. L. Beke +7
Over the last years several experimental and theoretical studies of diffusion kinetics on the nanoscale have shown that the time evolution differs from the classical Fickian law (k…
Degradation of Ag/Si multilayers during heat treatments
K. Kapta, L. Daroczi, Z. Papp +6
Microstructure changes during annealing of nano-crystalline silver and amorphous silicon multilayers (Ag/a-Si) have been studied by X-ray diffraction and transmission electron micr…
Laser-induced optical changes in amorphous multilayers
M. Malyovanik, S. Ivan, A. Csik +3
It is shown that the well-known blue-shift of the fundamental absorption edge in as-deposited compositionally modulated amorphous Si/Ge and As6Se94/Se80Te20 multilayers (with perio…
Pattern formation in SiSb system
A. Csik, G. Erdelyi, G. A. Langer +4
Thermal annealing of Si/Si1-xSbx/Si amorphous thin film tri-layer samples (x=18 and 24 at%Sb) under 100 bar Ar pressure results in an interesting pattern formation. In pictures, ta…
