The conductivity of the semiconductor due to directional movement therein of charge carriers - electrons and holes. Distinguish between the electron and hole conductivity semiconductor. Направленное движение носителей может быть вызвано двумя независимыми друг от друга факторами – действием электрического поля и неравномерным распределением носителей по… Continue Reading
P-type semiconductor or a p type semiconductor (from the Latin positive - positive) It called semiconductor, in the crystal lattice of which (rice. 1.4) contains trivalent impurity atoms, called acceptors. In such a crystal lattice of one of the covalent bonds remains unfilled. Свободную связь примесного атома может… Continue Reading
Electronic semiconductor or n-type semiconductor (from the Latin negative - negative) It called semiconductor, in the crystal lattice of which (rice. 1.3) in addition to basic (tetravalent) pentavalent impurity atoms contain atoms, called donor. В такой кристаллической решетке четыре валентных электрона примесного атома заняты в… Continue Reading
Proper semiconductors have a crystalline structure, characterized by a periodic arrangement of atoms in spatial lattice nodes. In such a lattice, each atom bonded to four mutually adjacent atoms by covalent bonds (rice. 1.2.), в результате которых происходит обобществление валентных электронов и образование устойчивых электронных… Continue Reading
solids, existing in nature are divided into amorphous and crystalline. Most of the currently used semiconductors are crystalline bodies, atoms are arranged in a specific order and form a spatial lattice. Almost all of them have a covalent bond, при которой взаимное притяжение… Continue Reading
