9. For organic semiconductors:     (a) The highest mobility in a sp2 bonded organic semiconductor is found in which 2D material?     (b) In materials with sp2 hybridized bonding, what new bonds are formed from the out-of-plane p-orbitals? (Greek letter)     (c) As the complexity (length, number of benzene rings) of your polymer chain increases, what happens to the energy gap between the highest occupied molecular orbit (HOMO) and lowest unoccupied molecular orbit (LUMO)?     (d) In your own words, explain why mobility in polymer organic semiconductors is low.

6. Pick one of these emerging ultra-wide bandgap materials: AlN, Ga2O3, diamond to use as the next-generation for power electronics. Discuss why you would choose it, the issues that need to be overcome with that material system, the ways to grow the bulk crystal, and techniques to grow epitaxial films of that material.
