AI Article Synopsis
- Researchers investigated the performance of organic field-effect transistors (OFETs) using a small molecule called C-BTBT, focusing on different electrode configurations.
- They compared contact resistance across various combinations of electrodes, including Ag and Au with oxide interlayers.
- The study found that using oxide interlayers reduced contact resistance and improved device performance, with specific explanations for the enhanced electrical properties based on the molecular structure at the interfaces.
Article Abstract
High performance, air stable and solution-processed small molecule 2,7-dioctyl[1]benzothieno[3,2-b]benzothiophene (C-BTBT) based organic field-effect transistors (OFETs) with various electrode configurations were studied in detail. The contact resistance of OFET devices with Ag, Au, WO/Ag, MoO/Ag, WO/Au, and MoO/Au were compared. Reduced contact resistance and consequently improved performance were observed in OFET devices with oxide interlayers compared to the devices with bare metal electrodes. The best oxide/metal combination was determined. The possible mechanisms for enhanced electrical properties were explained by favorable morphological and electronic structure of organic/metal oxide/metal interfaces.

Hydrogel-based sensors have been widely studied for perceiving the environment. However, the simplest type of resistive sensors still lacks sensitivity to localized strain and other extractable data. Enhancing their sensitivity and expanding their functionality to perceive multiple stimuli simultaneously are highly beneficial yet require optimal material design and proper testing methods.

Electrolytic glucose oxidation has garnered great interest in energy-saving hydrogen generation. However, high charge-transfer resistance and inefficient active centers have been recognized as the primary issues for poor electrochemical performance. In this study, for the first time, we offer a novel defect-rich CeO /β-Ni(OH) composite nanosheet-decorated Ni foam electrocatalyst (denoted as Ce@NF-GA), synthesized a unique hydrothermal approach under the co-participation of glycerol and acetic acid.

Infections with soil-transmitted helminths pose a significant threat to wildlife in enclosures, where transmission of these parasitic larvae is easier due to the limited space. Nematophagous fungi offer a promising solution as they can naturally control these nematodes. In this study, three nematophagous fungi (, , ) purchased from the non-profit global biological resource center ATCC were tested for their suitability as biological control agents.

The contaminated transformer oil is one of the major causes of failure in the power system. Detection and continuous monitoring of moisture content in transformer oil is required for the smooth operation of a system. In this paper, a Fractal-based Sinusoidal-shaped Capacitive Sensor (FSCS) is proposed to increase the contact area between capacitor plates and dielectric medium by 17.
