(2023). The capacitance/conductance and surface state intensity characteristics of the Schottky structures with ruthenium dioxide-doped organic polymer interface. Synthetic Metals, 292, 117243.0379-6779https://doi.org/10.1016/j.synthmet.2022.117243https://hdl.handle.net/11467/8671The electrical behaviors of the Schottky structures with a ruthenium dioxide (RuO2) doped-polyvinyl chloride (PVC) interface were executed with a wide frequency range (from 1 kHz to 5 MHz) and voltages. The interface was obtained by dispersing RuO2 nanopowder as colloidal particles into the PVC organic polymer using the ultrasonic irradiation method. The capacitance/conductance and surface state intensity (Nss) effects of this interface on the structure have been widely discussed. Remarkable increases in capacitance (C) and conductance (G/.) values were found, especially in the depletion zone. The series resistance of the structure (Rs) value decreases strongly with increasing frequency for + 3.5 V, down to a value of approximately 48.43 O at 5 MHz. Furthermore, the effect of the Rs is seen in the Cc and Gc/. curves in the weak and strong accumulation regions. While the maximum value of the Nss is 1.42 x 10(13) eV 1.cm(-2) at 0.478 eV, its minimum value is 1.23 x 1013 eV 1.cm (-) at 0.540 eV. The relaxation time (t) values change from 2.40 x 10(-5) to 2.03 x 10(-4) s in exponentially increasing values. It can be stated that there is an inverse relationship between the t and distribution of the Nss values. These distributions vary depending on the applied voltage and frequency.eninfo:eu-repo/semantics/closedAccessDoped-Organic InterfaceConductance MethodInterface StatesRelaxation TimeFrequency-Dependent CharacteristicsArticle292Q2WOS:000932338500001Q12-s2.0-8514407048510.1016/j.synthmet.2022.117243
