Edgars Imants Siliņš
Edgar Imant Silinsh (, , ''Edgar Aleksandrovich Silinsh''; 21 March 1927 – 26 May 1998) was a Soviet and Latvian scientist in the field of semiconductor physics and philosophy of science, academician of the Latvian Academy of Sciences (1992). Biography Edgar Silinsh was born the 4th child in a family of prosperous farmer Aleksandrs Siliņš (1875—1934) on the "Veclapsas" farmstead in Līgatne municipality of Riga district. During his school years, he was mostly interested in literature and history rather than in physical sciences. Due to the start of World War II and the death of his mother in 1943, E. Silinsh was forced to discontinue his education; nevertheless, in 1946 he took secondary school exams and enrolled at the Faculty of Chemistry of the State University of Latvia (SUL). The choice for natural sciences was rooted in Edgar's awareness of humanities being ideologically constrained in the Soviet Union. Yet he was forced to cease his studies even in the field ...

Līgatne
Līgatne (; ) is a town in Līgatne Parish, Cēsis Municipality in the Vidzeme region of Latvia. It is situated on the Gauja, Gauja River. The village of Līgatne was built around the paper mill, still extant, on the River Ligatne (river), Līgatne in the 19th century. Later it grew into a town and was then awarded city status in 1993. Līgatne Nature Trails The reserve known as the Līgatne Nature Trails is also located here, in the Gauja National Park, in the forest on the left bank of the Gauja River downstream from the paper mill. There are extensive paths through the nature reserve both for walking and for cycling, and there is a separate route for cars. There are also facilities for horse-riding and camping. The reserve was set up in 1975 for the protection and display of the diversity of species, both plant and animal, which are characteristic of Latvia. The animals here have been rescued from all over Latvia, either because they were injured, or because they had been ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Band Theory
In solid-state physics, the electronic band structure (or simply band structure) of a solid describes the range of energy levels that electrons may have within it, as well as the ranges of energy that they may not have (called ''band gaps'' or ''forbidden bands''). Band theory derives these bands and band gaps by examining the allowed quantum mechanical wave functions for an electron in a large, periodic lattice of atoms or molecules. Band theory has been successfully used to explain many physical properties of solids, such as electrical resistivity and optical absorption, and forms the foundation of the understanding of all solid-state devices (transistors, solar cells, etc.). Why bands and band gaps occur The formation of electronic bands and band gaps can be illustrated with two complementary models for electrons in solids. The first one is the nearly free electron model, in which the electrons are assumed to move almost freely within the material. In this model, the ...

Solid-state Physics
Solid-state physics is the study of rigid matter, or solids, through methods such as solid-state chemistry, quantum mechanics, crystallography, electromagnetism, and metallurgy. It is the largest branch of condensed matter physics. Solid-state physics studies how the large-scale properties of solid materials result from their atomic-scale properties. Thus, solid-state physics forms a theoretical basis of materials science. Along with solid-state chemistry, it also has direct applications in the technology of transistors and semiconductors. Background Solid materials are formed from densely packed atoms, which interact intensely. These interactions produce the mechanical (e.g. hardness and Elasticity (physics), elasticity), Heat conduction, thermal, Electrical conduction, electrical, Magnetism, magnetic and Crystal optics, optical properties of solids. Depending on the material involved and the conditions in which it was formed, the atoms may be arranged in a regular, geometric patt ...

Plzeň
Plzeň (), also known in English and German as Pilsen (), is a city in the Czech Republic. It is the Statutory city (Czech Republic), fourth most populous city in the Czech Republic with about 188,000 inhabitants. It is located about west of Prague, at the confluence of four rivers: Mže, Úhlava, Úslava and Radbuza, together forming the Berounka River. Founded as a royal city in the late 13th century, Plzeň became an important town for trade on routes linking Bohemia with Bavaria. By the 14th century it had grown to be the third largest city in Bohemia. The city was besieged three times during the 15th-century Hussite Wars, when it became a centre of resistance against the Hussites. During the Thirty Years' War in the early 17th century the city was temporarily occupied after the Siege of Plzeň. In the 19th century, the city rapidly industrialised and became home to the Škoda Works, which became one of the most important engineering companies in Austria-Hungary and later ...

Martin Pope
Martin Pope (born Isidore Poppick; August 22, 1918March 27, 2022) was an American physical chemist and professor at New York University. His discoveries of ohmic contacts and research in the fields of organic insulators and semiconductors led to techniques enabling organic semiconductors to carry relatively large currents, and to convert electricity into light and vice versa. These discoveries have had application in electrophotography, organic light-emitting diodes (OLED), photovoltaic cells, biological sensors, transistors, molecular electronics, and batteries. For his work, Dr. Pope was awarded the Davy Medal from the Royal Society in 2006. Biography Martin Pope was born in 1918 to Jewish immigrants from Ukraine. The second of four sons, Pope grew up on New York's Lower East Side. He attended the City College of New York, graduating with a bachelor's degree in chemistry in 1939.

Scopus
Scopus is a scientific abstract and citation database, launched by the academic publisher Elsevier as a competitor to older Web of Science in 2004. The ensuing competition between the two databases has been characterized as "intense" and is considered to significantly benefit their users in terms of continuous improvement in coverage, search/analysis capabilities, but not in price. Free database The Lens completes the triad of main universal academic research databases. Journals in Scopus are reviewed for sufficient quality each year according to four numerical measures: ''h''-Index, CiteScore, SJR ( SCImago Journal Rank) and SNIP ( source normalized impact per paper). For this reason, the journals listed in Scopus are considered to meet the requirement for peer review quality established by several research grant agencies for their grant recipients and by degree-accreditation boards in a number of countries. Scopus also allows patent searches from a dedicated patent dat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
