X-ray absorption near edge structure studies of Pb1-xMnxTe(In, Ga) systems
(International Journal of Materials Research, 2013)
The X-ray absorption near edge structure technique was employed for studies of coordination environments and valence states of impurity atoms (Mn, In and Ga) in a series of narrow band gap PbTe-based semiconductors. Impurity ...
Stability of nano-scaled Ta/Ti multilayers upon argon ion irradiation
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2011)
The effects of argon ion irradiation on structural changes in Ta/Ti multilayers deposited on Si wafers were investigated. The starting structures consisted of sputter deposited 10 alternate Ta (similar to 23 nm) and Ti ...
Ion beam modification of structural and electrical properties of TiN thin films
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2008)
A study of ion beam modification of structural and electrical properties of TiN thin films is presented. The layers were deposited by reactive ion sputtering on (100) Si and glass slide substrates to a thickness of similar ...
Coulomb correlated band structure of one-dimensional SrCuO2
(Solid State Communications, 1998)
The spin-restricted, spin-polarized, and LDA-I-U fully self-consistent linear muffin-tin orbital band structure for the one-leg ladder compound SrCuO2 has been studied. An extremely small band gap solution with negligible ...

The vibron dressing in alpha-helicoidal macromolecular chains
(Chinese Physics B, 2013)
We present a study of the physical properties of the vibrational excitation in alpha-helicoidal macromolecular chains, caused by the interaction with acoustical and optical phonon modes. The influence of the temperature ...
Photoluminescence and far-infrared spectroscopy of PbS quantum dots - Polyvinyl alcohol nanocomposite
(Optical Materials, 2008)
The nanocomposite consisting of PbS quantum dots with average diameter of 26 A and polyvinyl alcohol was characterized using photoluminescence and far-infrared spectroscopy. Photoluminescence spectra of nanocomposite, ...
Interchain coupling effects on large acoustic polaron in two parallel molecular chains
(Chemical Physics, 2013)
We examine the effects of the interchain coupling on the properties of the large adiabatic polaron in the two chain model. In dependence of the strength of the interchain coupling (gamma) two different types of polaron ...
Modification of phonon spectra due to vibron self-trapping in molecular crystals
(Physics Letters A, 2006)
Possible modification of the phonon spectra due to the presence of small-polaron arising on account of vibron (amid-I quanta) self-trapping in hydrogen-bonded molecular chains is discussed. We predict that small-polaron ...
The influence of polaron-phonon interaction on absorption spectra in molecular crystals
(Chemical Physics Letters, 2009)
We investigate theoretically the possible manifestation of the small-polaron effect in the IR absorption spectrum of the one-dimensional molecular crystals. Phonon-induced relaxation of small-polarons is taken into account ...
