Autor: I. V. Zhevstovskikh, Yu. V. Korostelin, M. N. Sarychev, V. V. Gudkov, G. S. Shakurov
Publikováno v: Physics of the Solid State. 62:2101-2104
Impurity Cr2+ ions in the CdSe crystal are studied by tunable EPR spectroscopy in the frequency range of 70–320 GHz. The discovered Jahn–Teller tetragonal distortions of the nearest environment of the chromium ion confirm the results of recent ul

Publikováno v: Semiconductors. 53:2012-2015
For silicon carbide, the problem of obtaining low-resistance ohmic contacts with improved service characteristics remains topical despite a significant body of experimental data. The influence exerted by the composition of Ni and TiAl metallization,

Publikováno v: Ukrainian Neurosurgical Journal, Iss 1, Pp 51-59 (2010)
Syndromes of neurovascular compression or hyperactive disorder (SHD) of cranial nerves at most patients are provocated by vascular compression of corresponding nerve’s root. But some authors deny vascular compression to be the main etiological fact
