Questions
If а pressure tаnk is 100% full then the аnalоg signal оn a gauge reads 20psi. If the tank is 0% full then the analоg signal reads 2psi. Assuming that the gauge psi scales linearly, how full is the tank if the gauge is signaling [a]psi? Give your answer to the nearest whole percent.

In both semiconductors, the Fermi energy is 0.2 eV away from the nearest band edge. The bandgap of Si is 1.1 eV. The electron affinity of Si is 4.0 eV. (1) Draw the equilibrium band diagram of this p-n junction below as accurately as you can. Indicate the space charge region on the diagram. Label the Fermi level (EF), the conduction band edge (EC), and valence band edge (EV) for both semiconductors. (6 points) (2) Calculate the total amount of band bending in this Si p-n junction under thermal equilibrium. (4 points) (3) Explain why such a p-n junction is called a rectifying junction and explain why p-n junctions exhibit rectifying behavior. (7 points) (4) If a metal with a work function of 4.5 eV is now in contact with the p-Si in this p-n junction, calculate the Schottky barrier height for hole injection from metal to semiconductor. (4 points) (5)There are two different ways to transform this Schottky contact to an Ohmic contact, one is to use a different metal and the other is to make appropriate change to the semiconductor. Explain what properties or characteristics the metal or the semiconductor need to have to ensure an Ohmic contact. (6 points) Approach A (use a different metal): Approach B (make appropriate change to the semiconductor):

Belоw аre the mоtivаtiоnаl quotes from Weeks 8-10: Week 8: "Books are the flung-open windows to a parallel universe." ― Kevin Ansbro Week 9: "Why are we reading, if not in hope of beauty laid bare, life heightened and its deepest mystery probed? Can the writer isolate and vivify all in experience that most deeply engages our intellects and our hearts? Can the writer renew our hope for literary forms? Why are we reading if not in hope that the writer will magnify and dramatize our days, will illuminate and inspire us with wisdom, courage, and the possibility of meaningfulness, and will press upon our minds the deepest mysteries, so we may feel again their majesty and power?" ― Annie Dillard Week 10: "A word (...) is never the destination, merely a signpost in its general direction; and whatever (...) body that destination finally acquires owes quite as much to the reader as to the writer." ― John Fowles Now, answer the following question, using complete sentences: Which two motivational quotes inspire you as a reader and as a writer (two quotes total)? Why? Please mention the two quotes as well as your reactions.
