Abstract The escalating interest in 2D nanoflakes‐based group‐IVA metal chalcogenides is attributed to their noteworthy properties, such as high electron mobility, exceptional chemical stability, and applicability across diverse scientific disciplines sensing, energy storage applications, supercapacitors, lithium‐ion batteries. This study introduces an innovative self‐powered photodetector based on chalcogenide nanoflakes (SnS 2 SnSe ) formed into nanoflowers a silicon substrate through the...
Herein, we report the novel nanostructural interfaces of self-assembled hierarchical ZnO nanotubes/graphene (ZNT/G) with three different growing times ZNTs on graphene substrates (namely, SH1, SH2, and SH3). Each sample was fabricated interdigitated electrodes to form hydrogen sensors, their sensing properties were comprehensively studied. The systematic investigation revealed that SH1 sensor exhibits an ultrahigh response even at a low detection level 10 ppm (14.3%) 100 (28.1%) compared...
Realizing bidirectional photodetection is essential for developing next-generation artificial neuromorphic systems, visual information processing, and future optoelectronic logic gates. Photodetectors are promising visible light communication systems due to their energy efficiency cost-effectiveness. Color shift keying frequently used in meet non-negative intensity modulation demands. However, requiring a minimum of two photodetectors with filters decode optical signals raises the device...
Granular activated carbon (GAC) materials were prepared via simple gas activation of silkworm cocoons and coated on ZnO nanorods (ZNRs) by the facile hydrothermal method. The present combination GAC ZNRs shows a core-shell structure (where is surface ZNRs) exposed systematic material analysis. as-prepared samples then fabricated as dual-functional sensors and, most fascinatingly, as-fabricated exhibits better UV H2 sensing properties than those GAC. Thus, structure-based sensor fast...
Molybdenum diselenide (MoSe2) is a promising gas sensing material due to its large surface-to-volume ratio, narrow band gap, and excellent absorptions. However, MoSe2-based sensors possess inferior response recovery at room temperature. In this context, assembly of hybrid structures can be an effective technique stimulate the intrinsic structural electronic properties MoSe2 nanosheets (NSs). Herein, we report interfacial science engineering design unique p–n hetero nanostructure for first...
Due to environmental problems such as global warming and ozone depletion, it is essential detect harmful UV rays from sunlight commercialize a clean energy source (H<sub>2</sub>), both issues require reliable sensor.
Abstract This article outlines a novel material to enable the detection of hydrogen gas. The combines thin‐film metallic glass (TFMG), ultra‐nanocrystalline diamond (UNCD), and ZnO nanorods (ZNRs) can be used as device for effective gas sensing. Three sensors were fabricated by using combinations pure ZNRs (Z), UNCD/ZNRs (DZ), TFMG/UNCD/ZNRs (MDZ). MDZ exhibited performance superior other configurations, with sensing response 34 % under very low concentrations (10 ppm) at room temperature....
Future innovation of optoelectronic industrial applications for energy saving devices such as self-powered sensors and photodetectors have gained much research attention.
Microstructural evolution of ultrananocrystalline diamond (UNCD) films in the bias-enhanced nucleation and growth (BEN-BEG) process CH4/Ar plasma is systematically investigated. The BEN-BEG UNCD possess higher rate better electron field emission (EFE) illumination (PI) properties than those grown without bias. Transmission microscopy investigation reveals that grains are formed at beginning for by applying bias voltage, whereas amorphous carbon forms first needs more 30 min formation...
Abstract We have designed photodetectors and UV field emitters based on a combination of ZnO nanowires/nanorods (ZNRs) bilayer diamond films in metal–semiconductor–metal (MSM) structure.
