Dielectric Function for Gold in Plasmonics Applications: Size Dependence of Plasmon Resonance Frequencies and Damping Rates for Nanospheres.
TL;DR: The improved, simple dielectric function for gold is given which accounts for the frequency dependence of the interband transitions over 1.8 eV and, in addition, for the finite size effects in gold nanoparticles.
Journal ArticleDOI
Highly mismatched crystalline and amorphous GaN1−xAsx alloys in the whole composition range
Kin Man Yu,Sergei V. Novikov,R. Broesler,I. N. Demchenko,Jonathan D. Denlinger,Zuzanna Liliental-Weber,F. Luckert,Robert W. Martin,Wladek Walukiewicz,C. T. Foxon +9 more
TL;DR: In this paper, the properties of GaN1−xAsx, a highly mismatched, immiscible alloy system that was successfully synthesized in the whole composition range using a nonequilibrium low temperature molecular beam epitaxy technique, were reported.
Journal ArticleDOI
Local atomic structure and magnetic ordering of iron in Fe-chitosan complexes.
Marcin T. Klepka,N. Nedelko,Jean-Marc Greneche,Krystyna Lawniczak-Jablonska,I. N. Demchenko,A. Slawska-Waniewska,Clóvis Antonio Rodrigues,Aline Debrassi,Cristiani Bordini +8 more
TL;DR: A detailed and consistent description of these complexes including, besides the overall magnetic behavior, the spin ordering and local atomic structure around Fe ions is presented.
Journal ArticleDOI
Full multiple scattering analysis of XANES at the Cd L3 and O K edges in CdO films combined with a soft-x-ray emission investigation
I. N. Demchenko,I. N. Demchenko,J. D. Denlinger,Maryna Chernyshova,Kin Man Yu,Derrick T. Speaks,Derrick T. Speaks,Paul Olalde-Velasco,Paul Olalde-Velasco,Oliver Hemmers,Wladek Walukiewicz,A. Derkachova,Krystyna Lawniczak-Jablonska +12 more
TL;DR: In this paper, X-ray absorption near edge structure (XANES) at the cadmium L3 and oxygen K edges for CdO thin films grown by pulsed laser deposition method, is interpreted within the real-space multiple scattering formalism, FEFF code.
Journal ArticleDOI
Effect of argon sputtering on XPS depth-profiling results of Si/Nb/Si
I. N. Demchenko,Yevgen Melikhov,Y. Syryanyy,Irina Zaytseva,P. Konstantynov,Maryna Chernyshova +5 more
TL;DR: In this article, two Si/Nb/Si trilayers with 9.5 and 1.3 nm thick niobium layer were studied using high-resolution (HR) XPS depth-profile techniques.
