Lateral disorder in Langmuir monolayers: theoretical derivations and grazing-incidence X-ray diffraction
L. R. Muftakhova, K. V. Nikolaev, A. V. Rogachev +3
Recent studies of the self-assembly of Langmuir monolayers have revealed novel forms of lateral molecular ordering. Such studies typically involve the use of grazing-incidence sync…
Conical diffraction of the synchrotron beam to probe the efficiency and morphology of blazed gratings
K. V. Nikolaev, L. I. Goray, P. S. Savchenkov +8
This study explores the use of synchrotron measurements as a nanometrology tool for blazed gratings. In grazing incidence geometry, one can measure both the conical diffraction and…
X-ray diffraction from smectic multilayers: crossover from kinematical to dynamical regime
V. V. Samsonov, K. V. Nikolaev, B. I. Ostrovskii +1
We study X-ray diffraction in smectic liquid crystal multilayers. Such systems are fabricated as freely suspended films and have a unique layered structure. As such, they can be de…
Probing Langmuir monolayer self-assembly in condensed and collapsed phases: grazing incidence X-ray diffraction and X-ray standing waves studies
K. V. Nikolaev, L. R. Muftakhova, G. M. Kuzmicheva +4
Ce-induced effects on the self-assembly of arachidic acid Langmuir monolayers was studied in this work. The monolayers were formed on the liquid subphase in the presence of Ce(III)…
Polygon-based unified Fourier-modal approach for diffractive optics simulations
K. V. Nikolaev, V. Soltwisch, M. A. Botchev +4
In this article, we derive a theoretical formalism that unifies the rigorous coupled wave analysis and the dynamical diffraction theory. Based on this formalism, we design a comput…
