Improvement of diode parameters in Al/n-Si schottky diodes with coronene interlayer using variation of the illumination intensity. Physica B: Condensed Matter, 527, pp. 1-6. https://doi.org/10.1016/j.physb.2017.09.1010921-4526https://doi.org/10.1016/j.physb.2017.09.101https://hdl.handle.net/20.500.12402/2873In present work, Coronene thin films on Si wafer have been deposited by the spin coating method. It has been ultimately produced Al/Coronene/n-Si/In Schottky diode. Current–voltage (I-V) measurements have been used to determine the effect of illumination intensity in the Schottky diodes. The barrier height (ΦB) values increased as ideality factor (n) values decreased with a increase in illumination intensity. The ΦB values have been found to be 0.697 and 0.755 eV at dark and 100 mW/cm2, respectively. The n values have been found to be 2.81 and 2.07 at dark and 100 mW/cm2, respectively. Additionally, the series resistance (Rs) values from modified Norde method and interface state density (Nss) values using current-voltage measurements have been determined. The values of Rs have been found to be 1924 and 5094 Ω at dark and 100 mW/cm2, respectively. The values of Nss have been found to be 4.76 × 1012 and 3.15 × 1012 eV−1 cm−2 at dark and 100 mW/cm2, respectively. The diode parameters are improved by applying the variation of illumination intensity to the formed Schottky diodes.eninfo:eu-repo/semantics/openAccessAttribution-NonCommercial-ShareAlike 3.0 United StatesBarrier HeightCoroneneIdeality FactorIllumination IntensityOrganic SemiconductorSchottky DiodeArticle52716Q2Q3
