Which of these statements is false?(a) As you go down column 4A in the periodic table, the elementalsolids become more electrically conducting. (b) Asyou go down column 4A in the periodic table, the band gapsof the elemental solids decrease. (c) The valence electroncount for a compound semiconductor averages out to fourper atom. (d) Band gap energies of semiconductors rangefrom ∼0.1 to 3.5 eV. (e) In general, the more polar the bondsare in compound semiconductors, the smaller the band gap.
