Unformatted text preview: he smallest? Is there a noticeable pattern in the band gap energy of 2III-V compounds related to the column momentum for particles like electrons and neutrons is E p / 2m , and for photons is E pc . Give III element? the energies in eV for each of the particles below for the wavelength shown: = 0.1 nm Particle = 1.0 nm electron E= E= neutron E= E= photon E= E= (b) Among the indirect materials listed in Appendix III, which one has the smallest bandgap energy, and what is that at room temperature? Which one has the largest bandgap energy, and what is that? 2. Based on Fig. 3.3, explain why the bandgap energy of a diamond crystal would increase (or decrease) with respect to that at room temperature when it is cooled to liquid nitrogen temperature. 5. The bonding model for InSb is pictured below. 3. The bonding model for InSb is pictured below. (a) Draw the bonding model for InSb depicting the removal of the colored In and Sb atoms.
