Vitebsk
Vitebsk or Viciebsk (russian: Витебск, ; be, Ві́цебск, ; , ''Vitebsk'', lt, Vitebskas, pl, Witebsk), is a city in Belarus. The capital of the Vitebsk Region, it has 366,299 inhabitants, making it the country's fourth-largest city. It is served by Vitebsk Vostochny Airport and Vitebsk Air Base. History Before 1945 Vitebsk developed from a river harbor where the Vićba River (Віцьба, from which it derives its name) flows into the larger Daugava River, Western Dvina, which is spanned in the city by the Kirov Bridge. Archaeological research indicates that Baltic tribes had settlements at the mouth of Vitba. In the 9th century, Slavic settlements of the tribal union of the Krivichs replaced them. According to the ''Chronicle of Michael Brigandine'' (1760), Princess Olga of Kiev founded Vitebsk (also recorded as Dbesk, Vidbesk, Videbsk, Vitepesk, or Vicibesk) in 974. Other versions give 947 or 914. Academician Boris Rybakov and historian Leonid Alekseyev ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heterojunction
A heterojunction is an interface between two layers or regions of dissimilar semiconductors. These semiconducting materials have unequal band gaps as opposed to a homojunction. It is often advantageous to engineer the electronic energy bands in many solid-state device applications, including semiconductor lasers, solar cells and transistors. The combination of multiple heterojunctions together in a device is called a heterostructure, although the two terms are commonly used interchangeably. The requirement that each material be a semiconductor with unequal band gaps is somewhat loose, especially on small length scales, where electronic properties depend on spatial properties. A more modern definition of heterojunction is the interface between any two solid-state materials, including crystalline and amorphous structures of metallic, insulating, fast ion conductor and semiconducting materials. Manufacture and applications Heterojunction manufacturing generally requires the use of mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semiconductor
A semiconductor is a material which has an electrical resistivity and conductivity, electrical conductivity value falling between that of a electrical conductor, conductor, such as copper, and an insulator (electricity), insulator, such as glass. Its electrical resistivity and conductivity, resistivity falls as its temperature rises; metals behave in the opposite way. Its conducting properties may be altered in useful ways by introducing impurities ("doping (semiconductor), doping") into the crystal structure. When two differently doped regions exist in the same crystal, a semiconductor junction is created. The behavior of charge carriers, which include electrons, ions, and electron holes, at these junctions is the basis of diodes, transistors, and most modern electronics. Some examples of semiconductors are silicon, germanium, gallium arsenide, and elements near the so-called "metalloid staircase" on the periodic table. After silicon, gallium arsenide is the second-most common s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Germanium Diode
A diode is a two-terminal electronic component that conducts current primarily in one direction (asymmetric conductance); it has low (ideally zero) resistance in one direction, and high (ideally infinite) resistance in the other. A diode vacuum tube or thermionic diode is a vacuum tube with two electrodes, a heated cathode and a plate, in which electrons can flow in only one direction, from cathode to plate. A semiconductor diode, the most commonly used type today, is a crystalline piece of semiconductor material with a p–n junction connected to two electrical terminals. Semiconductor diodes were the first semiconductor electronic devices. The discovery of asymmetric electrical conduction across the contact between a crystalline mineral and a metal was made by German physicist Ferdinand Braun in 1874. Today, most diodes are made of silicon, but other semiconducting materials such as gallium arsenide and germanium are also used. Among many uses, diodes are found in rect ...

Academy Of Sciences Of The Soviet Union
The Academy of Sciences of the Soviet Union was the highest scientific institution of the Soviet Union from 1925 to 1991, uniting the country's leading scientists, subordinated directly to the Council of Ministers of the Soviet Union (until 1946 – to the Council of People's Commissars of the Soviet Union). In 1991, by the decree of the President of the Russian Soviet Federative Socialist Republic, the Russian Academy of Sciences was established on the basis of the Academy of Sciences of the Soviet Union. History Creation of the Academy of Sciences of the Soviet Union The Academy of Sciences of the Soviet Union was formed by a resolution of the Central Executive Committee and the Council of People's Commissars of the Soviet Union dated July 27, 1925 on the basis of the Russian Academy of Sciences (before the February Revolution – the Imperial Saint Petersburg Academy of Sciences). In the first years of Soviet Russia, the Institute of the Academy of Sciences was perceived ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ioffe Institute
The Ioffe Physical-Technical Institute of the Russian Academy of Sciences (for short, Ioffe Institute, russian: Физико-технический институт им. А. Ф. Иоффе) is one of Russia's largest research centers specialized in physics and technology. The institute was established in 1918 in Petrograd (now St. Petersburg) and run for several decades by Abram Ioffe. The institute is a member of the Russian Academy of Sciences.

Karl Marx
Karl Heinrich Marx (; 5 May 1818 – 14 March 1883) was a German philosopher, economist, historian, sociologist, political theorist, journalist, critic of political economy, and socialist revolutionary. His best-known titles are the 1848 pamphlet ''The Communist Manifesto'' and the four-volume (1867–1883). Marx's political and philosophical thought had enormous influence on subsequent intellectual, economic, and political history. His name has been used as an adjective, a noun, and a school of social theory. Born in Trier, Germany, Marx studied law and philosophy at the universities of Bonn and Berlin. He married German theatre critic and political activist Jenny von Westphalen in 1843. Due to his political publications, Marx became stateless and lived in exile with his wife and children in London for decades, where he continued to develop his thought in collaboration with German philosopher Friedrich Engels and publish his writings, researching in the British Mus ...

Jean Jaurès
Auguste Marie Joseph Jean Léon Jaurès (3 September 185931 July 1914), commonly referred to as Jean Jaurès (; oc, Joan Jaurés ), was a French Socialist leader. Initially a Moderate Republican, he later became one of the first social democrats and (in 1902) the leader of the French Socialist Party, which opposed Jules Guesde's revolutionary Socialist Party of France. The two parties merged in 1905 in the French Section of the Workers' International (SFIO). An antimilitarist, Jaurès was assassinated in 1914 at the outbreak of World War I, but remains one of the main historical figures of the French Left. As a heterodox Marxist, Jaurès rejected the concept of the dictatorship of the proletariat and tried to conciliate idealism and materialism, individualism and collectivism, democracy and class struggle, patriotism and internationalism. Early career The son of an unsuccessful businessman and farmer, Jean Jaurès was born in Castres, Tarn, into a modest French pr ...
