About: Unit cell

An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

In geometry, biology, mineralogy, and solid state physics, a unit cell is a repeating unit formed by the vectors spanning the points of a lattice. Despite its suggestive name, the unit cell (unlike a unit vector, for example) does not necessarily have unit size, or even a particular size at all. Rather, the primitive cell is the closest analogy to a unit vector, since it has a determined size for a given lattice and is the basic building block from which larger cells are constructed.

  • Elementární (základní) buňka je nejmenší část krystalické struktury. Je to rovnoběžnostěn, který je jednoznačně určen třemi translačními vektory a, b, c a úhly, jimi sevřenými. Mnohonásobným opakováním této buňky se beze zbytku vyplní prostor krystalu. (cs)
  • In geometry, biology, mineralogy, and solid state physics, a unit cell is a repeating unit formed by the vectors spanning the points of a lattice. Despite its suggestive name, the unit cell (unlike a unit vector, for example) does not necessarily have unit size, or even a particular size at all. Rather, the primitive cell is the closest analogy to a unit vector, since it has a determined size for a given lattice and is the basic building block from which larger cells are constructed. The concept is used particularly in describing crystal structure in two and three dimensions, though it makes sense in all dimensions. A lattice can be characterized by the geometry of its unit cell. The unit cell is a section of the tiling (a parallelogram or parallelepiped) that generates the whole tiling using only translations. There are two special cases of the unit cell: the primitive cell and the conventional cell. The primitive cell is a unit cell corresponding to a single lattice point, it is the smallest possible unit cell. In some cases, the full symmetry of a crystal structure is not obvious from the primitive cell, in which cases a conventional cell may be used. A conventional cell (which may or may not be primitive) is a unit cell with the full symmetry of the lattice and may include more than one lattice point. The conventional unit cells are parallelotopes in n dimensions. (en)
  • 단위 격자(영어: Unit cell, also 단위 세포)는 물질 또는 원소를 이루는 기본적인 구조이다. 대표적인 4가지는 단순 입방 격자, 체심 입방 격자, 면심 입방 격자, 육방 밀집 격자가 있다. 단위 격자를 이루는 입자의 수는 다음과 같이 계산한다. 여기서: * a : 체심 * b : 면심 * c : 모서리 * d : 꼭짓점 (ko)
  • Komórka elementarna - w krystalografii - najmniejsza, powtarzalna część struktury kryształu, zawierająca wszystkie rodzaje cząsteczek, jonów i atomów, które tworzą określoną sieć krystaliczną. Komórka elementarna powtarza się we wszystkich trzech osiach, tworząc zamknięta sieć przestrzenną, której główną cechą jest symetria. Komórka elementarna ma zawsze kształt równoległościanu. Poprzez translacje komórki elementarnej o wektory będące całkowitymi wielokrotnościami otrzymuje się całą sieć krystaliczną kryształu. (pl)
