The compound gallium arsenide is a commonly used semiconductor,having an energy gap Eg of 1.43 eV. Its crystal structureis like that of silicon, except that half the silicon atoms are replacedby gallium atoms and half by arsenic atoms. Draw a flattened-outsketch of the gallium arsenide lattice, following the pattern.What is the net charge of the (a) gallium and (b) arsenic ioncore? (c) How many electrons per bond are there? (Hint: Consultthe periodic table in Appendix G.)
