a. What is the material that can naturally have electrons able to move across the band gap when supplied with additional energy (for example, pure silicon)? Oinsulator O intrinsic semiconductor O extrinsic semiconductor Ometal b. What is the name of the material that results from the addition of dopants to pure element in order for it to conduct electricity (for example, 0.0001% Al in Si)? Oinsulator O intrinsic semiconductor O extrinsic semiconductor Ometal

Al is a metal, Si is a semiconductor, P is a nonmetal. Order them from lower to higher energy gap between their valence and conduction bands: Select one: O a. Al < P < Si O b. P < Si < Al O. Si < Al < P O d. Al < Si < P

5. Cadmium sulfide, CdS, is used as a photoconductor in light meters. The band gap is about 2.4 eV. What is the greatest wavelength of light that can promote an electron from the valence band to the conduction band in cadmium sulfide?

Explain the following observation:
