Lyubomir Krastanov
Lyubomir Krastanov was a Bulgarian physical scientist specializing in meteorology, atmospheric physics and fundamental physics. One of the modes for growth of thin films, Stranski–Krastanov growth, is named after him and Ivan Stranski Ivan Nikolov Stranski ( bg, Иван Николов Странски; german: Iwan Nikolow Stranski; 2 January 1897 – 19 June 1979) was a Bulgarian physical chemist who is considered the father of crystal growth research. He was the founder o .... On the 12th of June 1959 he was elected the deputy president of the Bulgarian Academy of Sciences. References Further reading *Vesselinov, Markov Ivan.

Stranski–Krastanov Growth
Stranski–Krastanov growth (SK growth, also Stransky–Krastanov or Stranski–Krastanow) is one of the three primary modes by which thin films grow epitaxially at a crystal surface or interface. Also known as 'layer-plus-island growth', the SK mode follows a two step process: initially, complete films of adsorbates, up to several monolayers thick, grow in a layer-by-layer fashion on a crystal substrate. Beyond a critical layer thickness, which depends on strain and the chemical potential of the deposited film, growth continues through the nucleation and coalescence of adsorbate 'islands'. This growth mechanism was first noted by Ivan Stranski and Lyubomir Krastanov in 1938. It wasn't until 1958 however, in a seminal work by Ernst Bauer published in ''Zeitschrift für Kristallographie'', that the SK, Volmer–Weber, and Frank–van der Merwe mechanisms were systematically classified as the primary thin-film growth processes. Since then, SK growth has been the subject of inten ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ivan Stranski
Ivan Nikolov Stranski ( bg, Иван Николов Странски; german: Iwan Nikolow Stranski; 2 January 1897 – 19 June 1979) was a Bulgarian physical chemist who is considered the father of crystal growth research. He was the founder of the Bulgarian school of physical chemistry, heading the departments of physical chemistry at Sofia University and later at the Technical University of Berlin, of which he was also rector. The Stranski–Krastanov growth and Kossel–Stranski model are some of Stranski's contributions which bear his name. Biography Early life and studies Ivan Stranski was born in Sofia, the capital of the Principality of Bulgaria, as the third child of Nikola Stranski, pharmacist to the royal court, and his wife Maria Krohn, a Baltic German.* Ever since his childhood he suffered from bone tuberculosis, an incurable disease at the time. Stranski finished the First Sofia High School for Boys. Seeking ways to fight the illness, Stranski decided to study ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bulgarian Academy Of Sciences
The Bulgarian Academy of Sciences (abbreviated BAS; bg, Българска академия на науките, ''Balgarska akademiya na naukite'', abbreviated ''БАН'') is the National Academy of Bulgaria, established in 1869. The Academy, with headquarters in Sofia, is autonomous and consists of a Society of Academicians, Correspondent Members and Foreign Members. It publishes and circulates different scientific works, encyclopaedias, dictionaries and journals, and runs its own publishing house. The activities are distributed in three main branches: ''Natural, mathematical and engineering sciences''; ''Biological, medical and agrarian sciences'' and ''Social sciences, humanities and art''. They are structured in 42 independent scientific institutes, and a dozen of laboratories and other sections. Julian Revalski has been the president of the BAS since 2016. As of 2021, its budget was 117,8 million leva (€60,2 million). History As Bulgaria was part of the Ottoman E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Year Of Birth Missing
A year or annus is the orbital period of a planetary body, for example, the Earth, moving in its orbit around the Sun. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by change in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the planet, four seasons are generally recognized: spring, summer, autumn and winter. In tropical and subtropical regions, several geographical sectors do not present defined seasons; but in the seasonal tropics, the annual wet and dry seasons are recognized and tracked. A calendar year is an approximation of the number of days of the Earth's orbital period, as counted in a given calendar. The Gregorian calendar, or modern calendar, presents its calendar year to be either a common year of 365 days or a leap year of 366 days, as do the Julian calendars. For the Gregorian calendar, the average length of the calendar ye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
