Atomic layer deposition for TiO2 and TiN nanometer films

Ainabayev, Ardak; Bozheyev, Farabi; Zhuldassov, Abat; Lukasheva, Maria; Tynyshtykbaev, Kurbangali B.; Insepov, Z. (Materials Today: Proceedings, 2017-01-01)

Abstract In this work processes of atomic layer deposition (ALD) of TiO2 and TiN using ALD method and impact of thickness and composition of grown film on stoichiometry and morphology of deposited layer are investigated. ...
MoS2 nanopowder as anode material for lithium-ion batteries produced by self-propagating high-temperature synthesis

Bozheyev, Farabi; Zhexembekova, Anar; Zhumagali, Shynggys; Molkenova, Anara; Bakenov, Zhumabay (Materials Today: Proceedings, 2017-01-01)

Abstract Due to continuous rise of demand for powerful energy sources for portable applications, high energy density and efficiency rechargeable batteries are under constant development. Currently, the most widely used ...
Pulsed cathodoluminescence and Raman spectra of MoS2 nanocrystals at different excitation electron energy densities and laser wavelengths

Bozheyev, Farabi; Valiev, Damir; Nemkayeva, Renata (Journal of Luminescence, 2017-08-01)

Abstract Molybdenum disulfide nanocrystals exhibit direct dependencies of the Raman peaks' intensities and their positions on the thicknesses of the nanocrystals. This indicates dependencies of the electronic structure on ...
Pulsed cathodoluminescence of WS2 nanocrystals at various electron excitation energy densities: Defect induced sub-band gap emission

Bozheyev, Farabi; Valiev, Damir; Nemkayeva, Renata; An, Vladimir; Tikhonov, Alexander; Sugurbekova, Gulnar (Journal of Luminescence, 2017-12-01)

Abstract Pulsed cathodoluminescence spectra and luminescence decay kinetics of WS2 nanocrystals were studied under a high energy electron pulse excitation. Increasing electron energy density inputs to the WS2 nanocrystals ...
