WebThe crystal structure of silicon is identical with that of diamond and germanium with two atoms in the unit cell. In this respect it is a polyatomic crystal, but since the two atoms are mirror image twins there are simple relations between the complex coefficients in the two cellular expansions of the wave function. WebA solar cell is made of two types of semiconductors, called p-type and n-type silicon. The p-type silicon is produced by adding atoms—such as boron or gallium—that have one less electron in their outer energy level than does silicon. Because boron has one less electron than is required to form the bonds with the surrounding silicon atoms ...
