TL;DR: In this article, the effect of humidity on the electrical properties of the nanocomposite thin films was investigated by measurement of the capacitance and dissipation of the samples at two different frequencies of the applied voltage: 120 Hz and 1 kHz.

TL;DR: In this article, the effect of pressure on the properties of the fabricated field effect transistor (FET) with metal (aluminum) and semiconductor (copper phthalocyanine) Schottky junction was investigated.

TL;DR: In this paper, a zinc/polyvinyl alcohol-potassium hydroxide/carbon cell with PVA-KOH gel has been used as an electrolyte with a ratio of 60:40, while zinc and carbon rods served as electrodes.

Abstract: In this study, Ag/OD-MO/Ag surface-type diode was fabricated by drop-casting orange dye and methyl orange blend thin film from 1.0 wt.% aqueous solution, under the effect of an electric field, on a glass substrate with preliminary deposited silver electrodes. Geometrical length and width of the semiconducting channel between metallic electrodes were equal to 40 μm and 21 mm, respectively. The dark I-V characteristics exhibited strong rectification behaviour though both electrodes were from the same metal. The average value of rectification ratio (RR) was 27 and it was found that RR varies with applied voltage in the range of 1–40. The dark I-V characteristics were simulated by modified Shockley equation and space-charge limited currents (SCLC) approach. Different diode parameters were calculated from current-voltage characteristics. The diode showed non-ideal I-V behaviour with a quality factor greater than unity. Energy band diagram is proposed for the Ag/OD-MO/Ag surface-type diode.

TL;DR: In this article, the fabrication of organic semiconductor (OS) rectifiers and an investigation of rectifying antenna (rectenna) under the effect of microwave power was presented. But the rectifier was fabricated by thermal deposition of Ag, Au and NiPc thin films on a thoroughly cleaned glass substrate, and the measured I-V characteristics of the cell showed rectifying behavior.
