Special Issue Information

Dear Colleagues,

Nanostructured materials in various types of dimensions have received particular attention due to their promising applications as sensors in health care, early diagnosis, and environmental monitoring. Nanomaterials enable the miniaturization and integration of sensors in microsystems, leading to practical and portable sensing devices for specific analytes. In recent decades, various types of sensors have been developed with the assistance of nanomaterials, including the unique high-surface-area-to-volume ratio; biomolecule load capacity; easy preparation and functionalization; and optical, thermo-, electroconductive, and catalytic properties.

Thus, the aim of this Special Issue is to publish and disseminate original research data, review articles, communications, and short notes that focus on new (experimental or theoretical) advances, challenges, and outlooks concerning the preparation, characterization, and application of nanomaterials for sensors development. We invite contributions on topics that include but are not limited to various state-of-the-art sensing technologies.

Improvement of Photoresponse in Organic Phototransistors through Bulk Effect of Photoresponsive Gate Insulators
Materials 2020, 13(7), 1565; https://doi.org/10.3390/ma13071565 - 28 Mar 2020

In this study, we investigate the bulk effect of photoresponsive gate insulators on the photoresponse of organic phototransistors (OPTs), using OPTs with poly(4-vinylphenol) layers of two different thicknesses. For the photoresponse, the interplay between the charge accumulation (capacitance) and light-absorbance capabilities of a photoresponsive gate insulator was investigated. Although an OPT with a thicker gate insulator exhibits a lower capacitance and hence a lower accumulation capability of photogenerating charges, a thicker poly(4-vinylphenol) layer, in contrast to a thinner one, absorbs more photons to generate more electron–hole pairs, resulting in a higher photoresponse of the device. That is, in these two cases, the degree of light absorption by the photoresponsive gate insulators dominantly governed the photoresponse of the device. Our physical description of the bulk effect of photoresponsive insulators on the performance of OPTs will provide a useful guideline for designing and constructing high-performance organic-based photosensing devices and systems.
