(4) (5) Using equation ( ), a plot of dV/d(ln J) vs. J will give a straight line with the slope of Aeff • rs and the intercept of n/ , determining the n value. On the other hand, using equation ( ), a plot of H(J) vs. J will give a straight line with the intercept of n•B, and then B is determined from the n value. Equation ( ) and ( ) were applied to extract the Schottky parameters of a series of printed SBDs and a vacuum-deposited SBD, respectively. For the I-V data in the range of 0.2-0.5 V, plots of dV/d(ln J) and H (J) are shown in Figure B, E, H, K, N and C, F, I, L, O, respectively. Each experimental plots are on a straight line, indicating the good agreement with the diode equation. Thus, these results confirm the validity of equation ( ) and (5) in the selected voltage range. By fitting the plots by the least square method, the Schottky parameters of a series of printed SBDs and a vacuum-deposited SBD were determined and summarized in Table .
