Covalent bonds

Vedclass · Answer

(A) Semiconductors like $Si$ or $Ge$ form a crystal lattice through $covalent$ $bonds$. $n$-type semiconductors are formed by doping with pentavalent impurities (atoms with $5$ valence electrons),which provide extra electrons. $p$-type semiconductors are formed by doping with trivalent impurities (atoms with $3$ valence electrons),which create electron deficiencies or "holes". In both cases,the doping atoms substitute for the host atoms in the lattice and participate in the formation of $covalent$ $bonds$ with neighboring atoms.
