Pendulum Accelerometer with Digital Control and New Functionality
Autor: E. A. Deputatova, V. I. Grebennikov, V. V. Skorobogatov, L. Ya. Kalikhman, D. M. Kalikhman
Publikováno v: Journal of Computer and Systems Sciences International. 60:248-270
In this paper, we consider a compensation-type quartz pendulum accelerometer, a feature of which is the use of a digital feedback amplifier in the control loop (for the implementation of a discrete controller and algorithmic compensation for errors f

Resonance Interatomic Auger Transitions
Autor: V. I. Grebennikov, T. V. Kuznetsova
Publikováno v: Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques. 14:494-498
The interatomic Auger transitions in compounds containing atomic components with core levels close in energy are studied theoretically and experimentally. The Coulomb transitions of holes between such levels lead to resonant enhancement of the Auger

A wide energy range ab initio modeling of the electronic structure of valence states in Cu(In,Ga)Se2: Comparison with photoelectron spectra
Autor: T. V. Kuznetsova, V. I. Grebennikov, D.I. Radzivonchik, M. V. Yakushev, Alexey V. Lukoyanov
Publikováno v: Journal of Alloys and Compounds. 802:19-24
In this paper the electronic structure of the valence states in CuInSe2, CuGaSe2 and CuIn0.5Ga0.5Se2 is considered in details in a wide energy range up to 20 eV from the Fermi level. Examining the electronic structure within the LDA + U method we foc

The Effect of Copper on the Electronic Structure and Effective Masses of CuIn5Se8 Single Crystals Revealed by Angle-Resolved Photoemission Spectroscopy
Autor: V. I. Grebennikov, Friedrich Reinert, D. Vyalikh, D. Lupiszanski, T. V. Kuznetsova, M. V. Yakushev, I. V. Bodnar
Publikováno v: Physics of Metals and Metallography. 119:430-435
Angle-resolved photoemission spectroscopy (ARPES) has been used to study the electronic structure of InSe and CuIn5Se8 single crystals and determine the general patterns of its transformation after the introduction of copper. The main dispersion curv

Interference of First- and Second-Order Transitions in Resonant Photoemission
Autor: V. I. Grebennikov, T. V. Kuznetsova
Publikováno v: Bulletin of the Russian Academy of Sciences: Physics. 82:591-594
Resonant photoemission in narrow-band materials is characterized by the sum of first- and second- order transitions. Their quantum-mechanical interference results in enhancement of the valence-band spectrum and the emergence of an asymmetric dependen

X-ray circular magnetic dichroism in the presence of strong spin fluctuations
Autor: V. I. Grebennikov, T. V. Kuznetsova
Publikováno v: Bulletin of the Russian Academy of Sciences: Physics. 81:327-330
The use of X-ray magnetic circular dichroism (XMCD) spectra for determininghe t magnitude of atomic magnetic moments in compounds of rare-earth and transition elements is discussed. The standard sum rule approach often yields a magnitude of moments t
