There are four different types of band structures at 0 K. Among them, two are typified in metals, one in semiconductors and the last one in insulators. Which of the following statement/s is/are false? (i) In this band structure typified in metals, the outermost band is partially filled with electrons; (ii) In this band structure also typified in metals, there is an overlap of an empty band and a filled band; (iii) In the semiconductors, the band gap energy is narrower than insulators; (iv) In insulators, the band gap energy is wider than semiconductors. C. (iii) A. (i) E. None of the above D. (iv) B. (ii) Other:
