By impedance spectroscopy analysis, the conduction mechanism of the organic semiconductor of tris-(8-hydroxyquinolate)-aluminum (AlQ 3 ) is studied. Equivalent circuit analysis was performed with a series resistance and a pair of a parallel capacitance and a parallel resistance. It is found that the conduction mechanism seems to be space-charge limited current with exponential trap distribution,...
Organic thin-film field-effect transistors using organic semiconductor, perylene are fabricated, and electrical measurements are performed. The field-effect mobility of the device using perylene shows only p-type behavior while the electron and hole mobilities of its single crystal form are 5.5 and 0.5 cm 2 /Vs, respectively. Stacked layers of perlyene (a layer fabricated with low deposition...
