Vasyl Petrovich Kladko, Ukrainian physicist, killed in Vorzel
The toll of war is indiscriminate; all casualties are equally lamented through those they knew in life. We report this particular death only because of its relevance to our coverage.
Vasyl Petrovich Kladko, a celebrated Ukrainian physicist, was reportedly shot to death in Vorzel, outside Kyiv, on March 13. He was 65 years old.
According to the National Academy of Sciences of Ukraine, Kladko, the longtime head of department and deputy director of the Institute of Semiconductor Physics, was "barbarically shot by Russian occupiers" Sunday last, presumably as part of the Russian military's renewed push on Kyiv. Fighting intensified around Ukraine's capital, as well as in much of the country, as the war reached its 20th day on Tuesday. Vorzel, which neighbors Irpin, is about 20 miles northwest of Kyiv's city center, yet a mere eight miles from the city limits.
"The Department of Physics and Astronomy of the National Academy of Sciences of Ukraine is deeply saddened to announce that on March 13, this year in Vorzel, the Russian occupiers barbarically shot a remarkable experimental physicist, longtime head of the department and deputy director of the Institute of Semiconductor Physics. V.Ye. Lashkarev National Academy of Sciences of Ukraine, laureate of the State Prize of Ukraine in the field of science and technology , the prize. V.Ye. Lashkaryov of the National Academy of Sciences of Ukraine, Professor, Corresponding Member of the National Academy of Sciences of Ukraine Vasyl Petrovich KLADKO.
Ukrainian physics has suffered a heavy and unjustified loss.
He turned 65 two months ago, and found himself in Vorzel to relocate his family, hoping for safety. His wife and grandchildren managed to leave due to the significant deterioration of the situation, but he was delayed when the Russian occupiers entered Vorzel. And then what happened happened, and the reasons for which, apart from their intentions to destroy Ukraine and Ukrainians, are unknown.
Vasyl Petrovich Kladko was born on January 12, 1957 in the village of Ozero, Volodymyrets district, Rivne region.
In 1979 he graduated with honors from the Faculty of Physics of Chernivtsi State University. In 1982-1985 he studied at the graduate school of the Institute of Semiconductor Physics. In 1986 he defended his PhD thesis, in 2000 - his doctoral dissertation. In 2007 he was awarded the title of professor. In 2015, Vasyl Petrovich was elected a corresponding member of the National Academy of Sciences of Ukraine.
Among the most important scientific results are the following:
study of the physics of the processes of dynamic scattering of X-rays by real crystals in the most complex cases of the complex lattice structure and defective structure, which contains both deformation and compositional inhomogeneities;
the bases of structural diagnostics of real crystals which are based on features of dynamic scattering of X-rays in crystalline environments in the field of anomalous dispersion are offered and developed;
a two-dimensional model of long-range structural order was created for the spatial correlation function of vertically aligned quantum points, which allows to obtain the results of quantitative analysis of heterostructures from such points according to experimental data of high-resolution X-ray diffractometry;
laid the physical foundations of a new complex method of structural diagnostics of real crystals in the most complex case of a complex defective structure, consisting of both deformation and compositional inhomogeneities;
extending the field of research using quasi-forbidden reflexes to nanostructured objects (superlattices, structures with quantum dots and quantum dot arrays) established a number of interesting patterns: high sensitivity of quasi-forbidden reflexes to sublayers containing solid solutions, and defective structure of its individual layers and the possibility of separation of the contribution to the scattering capacity of such structures of each of the layers separately.
VP Kladko made a significant contribution to the development of physical and physical-technical bases for the formation of semiconductor nanostructures, had big plans to restore the electronics industry in Ukraine, as a true patriot did much to strengthen the defense capabilities of our country.
The Department of Physics and Astronomy of the National Academy of Sciences of Ukraine deeply mourns and expresses its condolences to the family and relatives of Vasyl Petrovich. The memory of him will always remain in our hearts.
We believe that his death, like the deaths of many Ukrainians, will not be forgiven and the occupiers will be severely punished.
Glory to Ukraine."
