Effect of impurities on the optical properties of KTP single crystals grown from flux
In the present work, KTP crystals have been grown by spontaneous nucleation technique in flux medium using K6P4O13 flux. 0.4-1 °C/h cooling rates were applied in the spontaneous nucleation process. The presence and amount of impurities has been determined by using XRF. The optical transmission spectra of impure KTP crystals in the UV–visible region are discussed. The transmission cut-off is cle...
متن کاملCu Induced Optical Transitions in MOCVD Grown Cu Doped GaN
Optical and structural properties of in situ Cu doped GaN thin films grown on sapphire substrates were optically investigated by means of Raman, photoluminescence (PL), and absorption spectroscopy. Different Cu concentrations in the films were analyzed by secondary ion mass spectroscopy (SIMS) and found to vary from 2x10 cm to 5x10 cm. Raman studies confirmed high crystalline quality of GaN:Cu ...
متن کاملInterplay of Microstructure and Magnetic Properties in Epitaxially Grown Co35Pd65 Alloy Films on Cu/Si(100)
The authors have investigated the correlation between magnetic properties, growth structure, and internal stress of epitaxially grown Co35Pd65 alloy films on Cu–Si(100) in the alloy thickness range from 1 monolayer (ML) to 10 ML. An in situ surface magneto-optical Kerr effects (SMOKE) study revealed that Co35Pd65 alloy films showed room-temperature ferromagnetism at a coverage of 2 ML with a st...
متن کاملOn the Chemistry and Physical Properties of Flux and Floating Zone Grown SmB6 Single Crystals
Recent theoretical and experimental findings suggest the long-known but not well understood low temperature resistance plateau of SmB6 may originate from protected surface states arising from a topologically non-trivial bulk band structure having strong Kondo hybridization. Yet others have ascribed this feature to impurities, vacancies, and surface reconstructions. Given the typical methods use...
متن کاملEvaluation of Physical Properties of B16N16 and B16N16-X(X=Cu, Cu+, Cu++)
To investigate the electromagnetic interaction of molecules inside the nanotubes, first, the structure of nanotubes B16N16 was optimized with hybrid density functional theory (B3LYP) using the EPR-II basis set, then Cu, Cu+, Cu++ were located in nanotube and we studied the total energy, band gap energy, electrical potential, changes of band gap energy in terms of total energy and dipole moment ...
