The paper presents the design and fabrication of a low-cost and easy-to-fabricate laser-induced graphene sensor together with its implementation for multi-sensing applications. Laser-irradiation of commercial polymer film was applied for photo-thermal generation of graphene. The graphene patterned in an interdigitated shape was transferred onto Kapton sticky tape to form the electrodes of a capacitive sensor. The functionality of the sensor was validated by employing them in electrochemical and strain-sensing scenarios. Impedance spectroscopy was applied to investigate the response of the sensor. For the electrochemical sensing, different concentrations of sodium sulfate were prepared, and the fabricated sensor was used to detect the concentration differences. For the strain sensing, the sensor was deployed for monitoring of human joint movements and tactile sensing. The promising sensing results validating the applicability of the fabricated sensor for multiple sensing purposes are presented.

This article outlines an ovel materialt oe nablet he detection of hydrogen gas. The material combines thin-film metallic glass (TFMG), ultra-nanocrystalline diamond( UNCD), and ZnO nanorods (ZNRs) andc an be used as ad evice for effective hydrogen gas sensing. Three sensors were fabricated by using combinations of pure ZNRs( Z), UNCD/ZNRs (DZ), and TFMG/UNCD/ZNRs (MDZ). The MDZd evice exhibited ap erformance superior to the other configurations, with as ensing response of 34 %u nder very low hydrogen gas concentrations (10ppm) at room temperature. Remarkably, the MDZ-based sensore xhibits an ultra-high sensitivity of 60.5 %u nder 500 ppm H 2 .T he MDZs ensor provedv ery fast in terms of response time (20 s) and recovery time (35 s). In terms of selectivity,t he sensors were particularly suited to hydrogeng as. The sensora chieved the same response performance even after two months, thereby demonstrating the superior stability. It is postulated that the superior performance of MDZ can be attributed to defect-related adsorption as well as chargecarrierd ensity.T his paper also discusses the respective energyb and models of these heterostructures and also the interface effect on the gas sensing enhancements. The results indicatet hat the proposed hybrid TFMG/UNCD/ZNRs nanostructures could be utilized as highperformance hydrogen gas sensors. 2À ).

Surface/Interface Engineering for Constructing Advanced Nanostructured Photodetectors with Improved Performance: A Brief Review

et al. 2020

View full text Add to dashboard Cite

Semiconductor-based photodetectors (PDs) convert light signals into electrical signals via a photon–matter interaction process, which involves surface/interface carrier generation, separation, and transportation of the photo-induced charge media in the active media, as well as the extraction of these charge carriers to external circuits of the constructed nanostructured photodetector devices. Because of the specific electronic and optoelectronic properties in the low-dimensional devices built with nanomaterial, surface/interface engineering is broadly studied with widespread research on constructing advanced devices with excellent performance. However, there still exist some challenges for the researchers to explore corresponding mechanisms in depth, and the detection sensitivity, response speed, spectral selectivity, signal-to-noise ratio, and stability are much more important factors to judge the performance of PDs. Hence, researchers have proposed several strategies, including modification of light absorption, design of novel PD heterostructures, construction of specific geometries, and adoption of specific electrode configurations to modulate the charge-carrier behaviors and improve the photoelectric performance of related PDs. Here, in this brief review, we would like to introduce and summarize the latest research on enhancing the photoelectric performance of PDs based on the designed structures by considering their surface/interface engineering and how to obtain advanced nanostructured photo-detectors with improved performance, which could be applied to design and fabricate novel low-dimensional PDs with ideal properties in the near future.
