In Organic Diodes, usually a high work function transparent metal is used as anode (PA) for hole injection and a low work function metal as cathode (pC) for electron injection. At the metal-organic- metal contact, a non-negligible built-in potential Vbi Pbi/q is present across the organic layer. Neglecting energy level shifts due to the interface dipoles, the built-in voltage is equal to: ФА- ФС ФА + ФС 0 2фС

Three archers each fire four arrows at a target. joe’s four arrows hit at points 10 cm above, 10 cm below, 10 cm to the left, and 10 cm to the right of the center of the target. all four of moe’s arrows hit within 1 cm of a point 20 cm from the center, and flo’s four arrows hit within 1 cm of the center. the contest judge says that one of the archers is precise but not accurate, another archer is accurate but not precise, and the third archer is both accurate and precise. which description applies to which archer? explain
